Installation
1. Locate and identify an approved compatible anchorage/structure. Be sure that the mounting
location is clean and free of debris.
2. Using a copy of the template provided (see Fig. 1a), drill four (4) each 7/16" (11mm) diameter
holes into the structure. Consideration should be given to allow sufficient clearance to tighten all
bolts and nuts.
3. Place the mounting bracket through the D-ring, centering the D-ring bar on the bracket.
4. Position the mounting bracket over the pre-drilled holes in the structure. Install one bolt through
a hole in the bracket and through the corresponding hole in the structure. Place the lockwasher
and nut onto the bolt, but do not tighten completely. Repeat with remaining three bolts.
5. Completely tighten using a torque value between 20-25 ft. lbs. Ensure the entire nut is engaged
on the threads of each bolt, and the device is securely fastened to the structure.
WARNING: Do not overtighten. Excessive tension can cause damage to the anchorage
system.
Removal: Loosen and remove all nuts, lockwashers and bolts to remove D-ring and mounting
bracket from the anchorage/structure.
