The back of the unit (near the roller) is labeled with the
width of each curtain and (for common footprints) a letter.
1. The back side of all wardens should be flush (A) and
measure the same distance (B) from the dock edge or
equipment it is protecting (C).
Position the inside edge of the wardens even with the
door jamb and the backs at least:
• 17in [432mm] from the dock edge (B), for units up to
11ft-5in [3.48M] C.O.W.* (D)
• 30in [762mm] from the dock edge (B), for units up to
11ft-6in to 16ft-5in [3.5m to 5.0m] C.O.W. (D)
Ensure the placement of the wardens do not interfere
with any door operation.
Footprint: Standard, go to Step 5.
(i.e.1 Storage (E1), 1 Receiver (E2)).
Footprint: Common, go to Step 2.
2. Unit "A": Position to begin the chain. The C.O.W.
between unit "A" and the first "B" unit must be within
5in [127mm] of the width dimension on the back of
unit "A".
3. Unit "B": Center each unit in the space available
between the respective doors being serviced.
Arrange, in correct sequence, any "B" units that vary
in C.O.W. Ensure the C.O.W. between the units is
within 5in [127mm] of the width dimension labeled on
the back of each unit's respective storage unit.
4. Unit "C": Position unit "C" and the latch side warden
to end the chain. Ensure the C.O.W. between unit "C"
and the latch side warden is within 5in [127mm] of the
width dimension on the back of unit "C".
5. After the units are within their respective service ranges,
shim the wardens as necessary to be plumb and level.
6. Complete "Anchoring to Concrete*" (page 8).

Anchoring to Concrete*
The Dok-Guardian Heavy Duty Safety Barrier requires a
minimum concrete thickness of 6.75in [170mm] to provide
proper unit support.
Tools Required:
• Hammer drill with 3/4in x 8in concrete drill bit
• Impact wrench (150ft-lbs [203Nm]) with 1-1/8in impact
socket
1. Tighten all rails and brackets securely before
anchoring the system to concrete.
2.
Titan HD Concrete Anchor Installation Instructions
Tools Required:
Hammer Drill with ¾” x 8” Concrete Drill Bit
Impact Wrench with 1-1/8” Impact Socket
Installation:
Drill a ¾” Diameter hole in the concrete. The hole should be drilled a minimum of 8” deep
or completely through the concrete.
Using a drill bit that is too small or excessively worn will make it very hard to install the
anchor. Using a drill bit that is too large will reduce the anchors load capacity.
Use compressed air to blow the concrete dust out of the hole. If this is not done, you may
not be able to tighten the anchor completely.
Using the Impact wrench and 1-1/8” socket, install the anchor through the base plate and
into the hole you drilled into the concrete.
Securely tighten all anchors with the impact wrench. Make sure the hex washer head is in
contact with the base plate.
Position the safety barrier in its
intended position. Use the base
plates of the warden as a template
and drill (6) 3/4in [19mm] diameter
holes a minimum of 8in [203.2mm]
deep (or completely through the
concrete).
– Drill the appropriate size hole in
the concrete per anchor being
used. The hole should be drilled
a minimum of 1in [25mm] deeper
than the length of the anchor or
completely through the concrete.
– Using a drill bit that is too small or
excessively worn will make it very
hard to install the anchor. Using a
drill bit that is too large will reduce
the anchor's load capacity.

Adjustment
1. Adjust curtains, after wardens are secured in place.
2. Pull the curtain across the door opening and secure
the latch bracket on the receiver warden.
3. Pull the curtain completely out until the round retainer
bar engages the inner storage support. Measure the
distance between the square latch bar and the latch
bracket.
4. If the distance is less than 3-1/4in [82.5mm],
the installation is complete.
5. If the distance is greater than 3-1/4in [82.5mm],
the latch bracket must be moved.
a. Walk the curtain back into its stored position.
b. Loosen the 3 bolts securing the latch bracket to
receiver warden.
c. Move the latch bracket away from the storage
warden the desired number of holes.
d. Tighten the 3 bolts securing the latch bracket to
receiver warden.
e. Refasten the latch bracket to receiver warden.
Tensioning
A
B
If the top of the curtain “sags” or seems to be loose:
1. Angle the curtain attachment on the roller so the top
of the curtain is pulled slightly tighter. With the curtain
pulled out and engaged, unroll the rest of the curtain
until the touch and hold fastener is accessible.
2. Lock the roller with a screwdriver, by inserting the
screwdriver through the hole in the top of the storage
support (A) and 1 of the slots (B) in the roller tube
concurrently.
3. Remove the curtain from the roller and angle the
curtain so the top of the curtain is slightly tighter. Hold
the roller while removing the screwdriver. Let the
curtain roll up slowly.
4. Disengage the curtain from the latch bracket and roll
the unit up 2 or 3 times. Engage the unit to see if the
curtain is tighter.
5. Repeat to add more angle, if necessary.

MAINTENANCE
Planned Maintenance
CUSTOMER:SALES ORDER #: SERIAL #: DATE:
DAILY MONTHLY INSPECT AND PERFORM THE FOLLOWING:
  Cycle the unit. Inspect unit for damage from impact.
  Look for tears in the curtain or steel that is bent or damaged.
–Ensure the concrete anchors are tight. Tighten with impact wrench.
–Latch the curtain in the protected position. Press against the curtain and make sure that the curtain travel is restricted before
4in [102mm] of curtain is allowed to unroll from the roller assembly.
–Unlatch the curtain and allow it to be rolled up by the roller assembly. Watch for any binding or loose edges on the curtain
that may get caught or inhibit the curtain from properly rolling up.
–Replace curtain if sewing becomes frayed or if there is signicant damage to the mesh.
–Clean the unit as necessary to maintain high visibility.
Exterior Use
The Dok-Guardian Heavy Duty Safety Barrier (without
interlock) can be used in an exterior environment.
Additional maintenance may be required, such as:
• Lubricating the roller bushing, checking the stitching of
the curtain, and checking for debris
• Additional lubrication, if the curtain is di󰀩cult to pull out
or the retraction of the curtain slows down
• Disassembling the roller and lubricating the spring
