Wall Mount model attaches to walls with four screws. Wall receptacle included to accept the strap end on the opposite side of a hallway or aisleway.
Clip-on Upright Mounted models use clips to attach quickly to warehouse uprights, and detach just as easily. Available in standard (fits uprights with holes measuring 1-1/2" apart) and adjustable (moveable clips fit uprights with holes between 1" and 3-1/2" apart). The S-hook at the end of the belt attaches to the belt itself after wrapping around the opposite upright.
The Rack Beam Mounted model snaps onto a 2-3/4"W beam. You can attach to the opposite side by wrapping the belt around the opposite upright and fastening the S-hook to the belt.
The Bolt-on Rack Upright Mounted model uses a wing bolt to attach to warehouse uprights, so it's not as easily moved as other models, but works perfectly on an aisle that routinely needs to be closed. The S-hook at the end attaches to the belt after wrapping around the opposite upright.
