DO NOT USE A PVC SLEEVE
THAT DOES NOT MEET ALL OF
THESE REQUIREMENTS.
Installation of PVC Sleeve for
Aluminum Post
Cut PVC sleeves to 12 in (304.8
mm), and cast sleeves into freshly
poured concrete of 2,000 PSI (13.8
MPa) or greater. Use duct tape to
seal the ends of the PVC sleeve,
preventing fresh concrete from
filling the sleeve. The PVC sleeve
must not be cast into concrete
within 3-1/2 in (88.9 mm) of any
concrete edge. When stirrups
exist in the column within 2-1/2 in
(63.5 mm) of the top surface, the
minimum column size must be no
less than 12 in (304.8 mm) in either
direction. When no stirrups exist,
the minimum column size must be
no less than 17 in (431.8 mm).
PVC sleeve should be plumb and
must be cast to a minimum depth of
11 in (279.4 mm). Ensure the PVC
sleeves do not float upwards in
the concrete before it sets. To help
keep sleeves from floating, punch
a small air hole through the duct
tape on the bottom of the sleeve,
and use a vertical 2x4 in the sleeve,
nailed to the top of the form. This
method will also help ensure the
sleeve stays plumb.
A sleeve should normally be placed
at the center of the column section.
This will minimize the tendency to
split the column. When sleeves are
placed at the center of the column
section, and when column ties exist
in the concrete within 2-1/2 in (63.5
mm) of the top surface (thereby
crossing the potential fracture
surface), the minimum column
size permitted is 12 in (304.8
mm) measured perpendicular to
the direction of the span of the
lifeline system. When there are
no such ties, the minimum column
dimension measured perpendicular
to the span of the lifeline system is
17 in (431.8 mm). Sleeves should
never be placed closer than 3-1/2
in (88.9 mm) to any edge of the
column cross-section.
When possible, request that a
column tie be located approximately
2 in (50.88 mm) below the top
surface of the column pour (Only

The aluminum post
is 7 ft-6 in (2.29
m) long. With a
12 in (304.8 mm)
embedded sleeve
to support the post,
the height of the
horizontal lifeline is
approximately 6 ft-6
in (1.98 m) above
the poured height
of the column. At
this height, the average employee
should pass easily under the cable
and conveniently reach it to attach
a self-retracting device.
It is easier and safer to assemble
as much of the SAFELINK Sys-
tem as possible before raising the
assembly to the elevated location.
Generally, the horizontal lifeline
can be attached to the posts before
inserting the posts into the column
tops. Final tension of the horizontal
lifeline, however, must always be
completed with the posts set into
the sleeves.
Reinforced Cross-Arm Strap
To secure the Cross-Arm Strap,
wrap the strap around the concrete
column at a height of at least 6
ft-6 in (1.98 m) above the walking
/ working surface using a choker
hitch. This is done by passing
one end of the strap through the
other end and cinching. Attach
the STOPLINK Brake by use of a
carabiner. Secure the other end of
the lifeline to column by tensioning
the line as required.
10,000 lb (4535.92 kg) Removable
Concrete Anchor
The Removable Concrete Anchor
is a reusable concrete anchor
designed to be used with horizon-
tal lifelines. This device is made
for use with concrete columns or
walls with a compressive strength
of 3,000 PSI (20.7 MPa). The
10,000-lb (4535.92 kg) rating is in
any direction up to 90º when placed
in concrete. Install the anchor in
accordance with user instructions.
Attach STOPLINK Brake by use
of carabiner to Concrete Anchor
eyelet.
RebarLink
The RebarLink Bracket is to be
installed 6-1/2 ft (1.98 m) above
the working surface. With the
eye-bolt facing outward, place the
bracket face perpendicular to the
front of the rebar, centered on the
cage. Slide the supplied cinching
rebar bolts through both plates
and tighten together with supplied
wing nuts so that the Rebar Link is
tightened onto the rebar cage
(See Figure 2).
NOTE: When using the RebarLink,
Aluminum Posts are not used.
FormLink
The FormLink Bracket must be
attached to the base of a rebar
cage. Receiver sleeve must face
the direction of tension in the
system. To attach the FormLink
Bracket to the base of the rebar
cage, place the front and back
bracket at the top of the concrete
base. Slide the threaded bars
through the holes on the front
bracket into the slots of the back
bracket. The front and back panels
of the FormLink Bracket must
capture a minimum of six (6) #7 or
larger rebar, two (2) with the front
panel and two (2) with the back
panel, with the threaded bars.
Hand-tighten all four (4) wing nuts,
then add an additional 1/2 in (12.7
mm) turn to secure.
INSTALLATION—ALUMINUM POSTS 10
Insert Aluminum Post
Each Aluminum Post has two (2)
sets of 9/16 in (14.29 mm) holes set
4 in (101.6 mm) apart and at 90º for
the eye-bolts. Install eye-bolts into
the Aluminum Post.
Insert aluminum post into PVC
Sleeve, or applicable receiver
sleeve on the anchorage connector.
Concrete must have a cured
compressed strength of 2,000
PSI (13.8 MPa) for system use.
Aluminum post must be inserted into
PVC sleeve.
