The Power-Rack Stanchion is made entirely from glass-reinforced nylon, these stanchions offer greater corrosion resistance than classical metal stanchions. The interlocking design allows the arm to 'lock' into nine different levels on the 14 1/4" stanchions and fourteen on the 17 1/2" stanchion. Glass-reinforced polyurethane stanchions are available as a special order. Contact Unistrut for pricing and availability.
Dimensions: The stanchion back has 9/16" x 15/16" holes to accept fasteners for mounting. There are two mounting holes in the 21 3/8"long stanchion and three in the 33 5/16" long stanchion. Thickness at the slotted mounting holes is 1 7/8". The mounting holes are spaced on 12" centers and require 1/2" diameter fasteners.
Installation: The Stanchions can be anchored into existing concrete structures using any industrial anchoring system. For new concrete structures, the Stanchions can be mounted to fiberglass concrete embedment channel and attached with 1/2" channel nuts and 1/2"x 3" Fiberfast Bolts.
Fire Retardance: Power-Rack materials meet or exceed the requirements of UL94 HB.
Loading: The recommended allowable loads on Power-Rack Stanchions vary depending upon the position of the arm. Use these guidelines for a safe, reliable installation:
*Total load on any one arm should not exceed 800 lbs.
*The sum of the loads on an arm multiplied by their distances to the wall
stanchion should not exceed 1200 in./lbs.
Example: A cable weighing 200 lbs. is positioned on an arm at a distance
of 5" from the wall stanchion.
If the total load is less than 800 lbs and the sum of the load multiplied by their distances to the wall stanchion does not exceed 1200 in./lbs., then the system is adequate. In this case,
Total load (200<800 lbs) = OK
Tot. moment (200x5 in. = 1000<1200 in./lbs.) = OK
