Product & Installation Manual: Sentryline III Non-Release Terminal End
Sentryline Terminal End III Non-
Release Terminal End
Introduction
The Sentryline Terminal End III is used to
anchor high tensioned 4 cable barrier system.
All cables connect to the “non-releasing” ground
anchor bracket that is attached to the concrete
foundations. A series of Sentryline II posts of
increasing length taper the cables from the ground
up to the required cable height for the Length of
Need barrier system.
The Sentryline Terminal End III has been
designed and tested to meet the evaluation criteria
of NCHRP 350 Test Level 3 (TL-3) for a cable
barrier system terminal end without releasing the
cables from the anchor point. This non-release
mechanism allows the system to remain anchored
following an impact and reduces the need for
immediate maintenance or repair and reducing the
hazard to other road users.
The Sentryline Terminal End III can be installed
with three different forms of concrete anchorage.
The system has been designed to prevent damage
from any in-ground components during an impact
from an errant vehicle, allowing for quick and cost
effective repairs. The Sentryline Terminal End III
can be used to anchor Sentryline Cable Barrier
Systems on new installs or to retrot to existing
Sentryline installations.
Training Outcomes
By the end of the training installers will be able to
identify each component of the Sentryline Terminal
End III as well as safely installing it as per product
specications and installation manual.
By the end of the training workers will also know
the correct PPE, that is required to be worn during
installation.
By the end of the training workers will know the
correct methods required to handle and install
the components of the Sentryline Terminal End III
system.
System Overview
The Sentryline Terminal End III is designed to
provide acceptable structural adequacy, minimal
occupant risk and safe trajectory as set forth in
NCHRP 350 for cable barrier system terminal ends.
When impacted by an errant vehicle, the cables
remain rmly engaged in the ground anchor
reducing the need for immediate maintenance or
repair. During an end-on impact or when struck
from the reverse angle, the vehicle pushes the
cables downward and safely traverse over the
system. When impacted on the side of the system,
the Sentryline Terminal End III will redirect the
vehicle along the face of the barrier system,
bringing it to a controlled stop.
The Length of Need (LoN) of the Sentryline
Terminal End III is dened as 8m downstream
from the non-releasing ground anchor. This is the
location along the barrier system at which re-
direction occurs and is known as the Point of Need
(PoN).
Following an impact with the system, the cables
will remain attached to the ground anchor bracket.
Repair of the system is completed by replacing any
bent or damaged posts.

Product & Installation Manual: Sentryline III Non-Release Terminal End
Limitations and Warnings
The Sentryline Terminal End III has
been rigorously tested and evaluated per
the evaluation criteria in the NCHRP 350
guidelines for gating, re-directive cable barrier
system terminal end. The impact conditions
recommended in NCHRP 350 are intended to
address typical in-service collisions.
The Sentryline Terminal End III allows an
impacting vehicle to remain on its wheels in a
safe and predictable manner under the NCHRP
350 impact conditions. It is imperative that
the system is installed as per manufacturers’
specication.
Vehicle impacts that vary from the NCHRP 350
impact conditions described for cable barrier
system terminal ends may result in signicantly
different results than those experienced in
testing. Vehicle impact characteristics different
than, or in excess of, those encountered in
NCHRP 350 testing (weight, speed and angle)
may result in system performance that may not
meet the NCHRP 350 evaluation criteria.

supplied for this product.
Note: Concrete foundations will have to be
designed by a local geotechnical engineer if soil
conditions on site do not meet the required level
described in the manual.
Depending on the application and circumstances
at the site, installation and assembly of the
system should take one person less than 20
minutes once the concrete foundation piles are
poured and set.
The Sentryline Terminal End III is an engineered
safety device. Before starting installation ensure
familiarity with the makeup of the terminal end.

System Design and Design
Considerations
Kerbs
As with all road side safety hardware, the
Sentryline Terminal End III has been designed
and tested so that the centre of gravity of the
impacting vehicle is at a constant height in
relation to the system. For this reason, it is
preferred that kerbs or channels are not in front
or behind the terminal end as they may result
in altering the height of the vehicle at impact. If
there is no option but to install near a kerb advice
should be followed from the Road Controlling
Authority’s guidelines.
Flare Rate
The preference is to not are the Sentryline
Terminal End III system. If this is unavoidable
then the maximum are rate should be 30:1 over
the entire length of the terminal end.
Undulating Ground Conditions
Site specic grading may be necessary to ensure
that there are no ‘humps’ or ‘hollows’ that may
signicantly alter the impacting vehicles stability
or substantially alter the cable heights in relation
to the ground. The non-releasing ground anchor
is required to be installed level and centred on
the barrier system line.
Care must be taken to ensure all posts in the
Sentryline Terminal End III are installed to the
correct height, alignment and orientation. It is
strongly recommended that smoothing of uneven
ground conditions be completed along the length
of the terminal end.
Clearzone
The Sentryline Terminal End III is a gating,
non-energy absorbing terminal end and
therefore requires a clearzone directly behind
as recommended by Road Controlling Authority
guidelines.
Vehicles impacting gating end terminals tend
to continue through the barrier system possibly
impacting xed objects or other hazards. It is
recommended that guidelines for the hazard free
area of a gating terminal be followed as stated in
AS/NZS 3845.
AS/NZS 3845 requires that a Hazard Free Zone
‘immediately behind and beyond the terminal
shall be reasonably traversable and free from
xed object hazards. If a clear run-out path is not
possible, this area should be similar in character
to adjacent unshielded roadside areas.
Tension
The Sentryline Terminal End III is designed to
anchor 4 high tensioned cable barrier systems.
Please refer to the section titled ‘Tensioning the
Barrier System’ for instructions on how to tension
the barrier system that is being installed.
Note: Do NOT tension a barrier system for seven
days after the foundation piles have been cast.

comprises of 7 terminal posts of varying lengths.
The rst post is located 2.0m from the location of
the ground anchor bracket. All remaining posts
are installed at a spacing of 1.5m.
> Care must be taken to ensure the correct
post spacing is ALWAYS used during the
installation.
> Care must be taken to ensure the posts are
orientated correctly during installation and to
ensure the cables do not cross.
> Care must be taken to ensure the line posts
are installed at the correct height, as detailed
below.

Product & Installation Manual: Sentryline III Non-Release Terminal End
Foundation Options
For the Sentryline Terminal End III to provide
sufcient anchoring strength to the cable barrier
system it relies on the design of the concrete
foundation anchor and the surrounding soil
conditions on site. Soil conditions can have
different characteristics that will affect the
strength of the concrete foundations and may
interfere with the performance of the system.
The Sentryline Terminal End III has been
designed to be used with an in-situ concrete
rectangular anchorage block. Alternative designs
can be used with the approval of the roading
authority and local geotechnical engineer.
Typical alternative designs include:
- Pile and and pile cap
- Alternative shaped in-situ rectangular block
The selection of the most suitable design option
will depend upon the soil type and geometric
constraints of the site.
Note: All technical information required to assist
in designing a site specic foundation is available
from ACP.
IF SOIL CONDITIONS ON SITE DO NOT MEET
OR EXCEED THE REQUIRED STRENGTH,
SITE SPECIFIC FOUNDATIONS MUST BE
DESIGNED BY A LOCAL GEOTECHNICAL
ENGINEER.
Length of Need
The length of need (LoN) of the Sentryline
Cable Barrier System connected to a Sentryline
Terminal End III system is dened as Post 5 at
the transition from the terminal end to the barrier
system, 8.0m downstream from the ground
anchor bracket.
Note: As per the LoN design section of the
Roading Control Authorities guidelines, care must
be taken when calculating the actual length of
a barrier system required verses the theoretical
length of need. The physical placement of the
Sentryline Terminal End III must be no closer
than Post 8 at the beginning of the LoN.

Construction of Anchor Blocks
Sentryline Terminal End III has been designed
with an in-situ poured rectangular ground anchor
block. Alternative designs are possible with
approval from the local roading authority and
geotechnical engineer.
Step 1
Excavate the required anchor hole in accordance
with Sentryline III drawings. Refer to Sentryline
Terminal End III foundation drawings for required
dimensions.
The orientation of the excavation is required to
be tangential with the line of the barrier system
and centred on the centreline of the system.
The walls of the excavation shall be vertical or
undercut (where possible). All loose spoil should
be removed from the excavation.
Step 2
Using a set of bolt cutters or equivalent, clip out
sufcient number of grids from the reinforcing
mesh to allow it to t over the anchor bracket.
Where possible the opening should not be
greater than one grid larger than the size of the
anchor bracket when installed.

Product & Installation Manual: Sentryline III Non-Release Terminal End
Step 3
Suspend the anchor bracket and reinforcing
mesh in the excavated rectangular hole in
accordance to Appendix A, using the two
temporary support frames and lightweight
strapping (as shown in the image below).
Strapping of the reinforcing mesh may also be
required to suspend it 75mm below ground level.
Once the anchor bracket and reinforcing mesh
has been placed in position, the installer needs
to cross check that the anchor brackets are
aligned with the posts using the string line and
the middle of the anchor bracket nger plate
(see Appendix B) and the middle of the rst post
(refer to Appendix A) are exactly 2 meters apart
as stated in Appendix A. We also recommend
the installer marks the side of the ground (refer
to image below) in accordance with the correct
position as a visual point of reference should
the pouring of wet cement in Step 4 pushes or
moves the support frames as shown in the below
image.
Step 4
Using 25 MPa structural concrete, ll the
excavated rectangular hole and agitate/vibrate to
allow even distribution while ensuring the anchor
bracket remains in the correct position.
Continue pouring concrete to the top of the
levelling bar plate located adjacent to the nger
plate.
.
Step 5
While the cement is wet, trowel around the
surface of the anchor bar plate to provide
adequate fall away from the wire ropes swaged
ends and ttings.

Construction of Post Footings
Step 1
Establish the desired post spacing and alignment
in accordance with Sentryline III Terminal End
drawings. The rst post should be 2.0m from
the ground anchor bracket, with all remaining
posts spaced at 1.5m centres for the length of
the terminal end. Care must be taken to keep the
post footings tangential to the barrier system and
in-line with the ground anchor bracket.
Step 2
Excavate or auger postholes of 300mm diameter
to a minimum depth of 750mm.
Ensure all spoil is removed from the excavation.
Step 3
Place a string line from the centre of the ground
anchor bracket to the centre of the line posts of
the barrier system. The string line should pass
over the centre of each post hole excavation.
Step 4
Pour 25 MPa structural concrete to within 50mm
from the ground level.

cement in alignment with the string line (as
shown in the below image). Once the rebar ring
is positioned correctly, ll the remaining hole with
concrete to be ush with the ground level.
Step 6
Gently move the string line aside while pushing
the post sleeve into the wet concrete penetrating
the rebar ring. When the string line is released,
the string line should be positioned over the
middle of the post sleeve.
To ensure the correct vertical placement of the
post sleeve, insert the respective post using
a level to cross check the sleeve is positioned
correctly prior to the concrete curing.
Care must be taken to ensure:
> the post sleeve is positioned within the rebar
ring, aligned with the string line and is level
with the ground.
> the post are placed in accordance to
spacing as shown in Appendix A.
> the height and alignment of each post meets
the tolerances stated on Page 8 and in
Appendix D.

Step 7
The post sleeve will initially be buoyant in the wet
concrete requiring constant pressure to ensure
it remains at ground level. For ease, we suggest
temporarily placing the post across the sleeve
while the wet concrete begins curing. This would
generally take 5-10 minutes. Failure to apply
appropriate pressure in the early curing stage
may result in the socket lifting, as shown in the
below image. If the post sleeve lifts during curing
stage as shown in the below picture, the hole will
need to be dug-out and the process repeated.
Step 8
Place the post covers into the sockets to prevent
debris from entering the sockets.
Assembly Sequence
Step 1
It is recommended that that concrete used for
the construction of anchor blocks and post
footings be cured for a minimum period of seven
days prior to completing the assembly sequence.
Step 2
Remove the post covers from the sockets and
inspect to ensure the sockets are free of debris.
Remove any debris if present.

Step 3
Insert the posts into each socket, ensuring the
correct posts are placed in each socket, resulting
in a gradual tapering up of the posts from the
rst post towards the length of need. Ensure the
orientation of the posts is consistent with the
designer’s instructions. Ensure that the beginning
of the design LoN is at or downstream from the
terminal PoN at Post 5.
Step 4
Note check cables are not required in all states
of Australia. Check your state road controlling
authority conditions.
If required, install each of the check cables by
sliding one loop end over each barrier cable
PRIOR TO SWAGING. Machine swage the
cables as per the procedure described in Step 8
Connecting the Machine Swage Fittings’ of the
Sentryline II Cable Barrier System installation
manual.
Place the rst two cables into the outer most
slots of the ground anchor bracket and then run
these through the central slot of the posts.
Next, place a barrier cable in each of the two
inner slots and run these cables through the
corresponding side slots on the posts i.e. cable
in left hand central slot of bracket runs through
the left hand slots on post and cable in right
hand in corresponding right slot on post (except
for Post 1 which does not contain side slots
therefore cables are passed on the outside).
If check cables are installed, attach the free loop
end of the check cable to the ground anchor
bracket. The two left hand check cables should
be attached to the left hand side of the ground
anchor via the supplied shackle. Repeat this
procedure for the two right hand side check
cables to the right side of the ground anchor.

Step 5
a) Post 1 consists of a top slot only with no
side slots. The wire rope should be aligned in
accordance with all prior posts, with the two lower
cables passing around the sides of the post. The
central cables should sit directly into the central slot
as shown.
b) Ensure all cables are correctly located in the side
slots and top slot of the posts. The cables should t
rmly to the bottom of the individual slots, and be
located below the barbed details on the side slots.
Step 6
When all the ropes have been installed, t the plastic
caps to the posts, pressing down rmly until the cap
sits ush with the top of the posts.
Ensure that the cables in the side slots of the posts
have been captured behind the ngers of the plastic
caps.
Step 7
Tension the barrier system, as per the requirements
noted in the section titled ‘Tensioning the Barrier
System’.
