*All Load Capacities include a 2.5 to 1 Factor of Safety. 

This product will not resist uplift. In the animation below notice how the screw drops into the pipe and the wing nut rests directly on the edges of the pipe where no positive connection between the pipe and bottom side of the wing nut is made. If uplift resistance is needed, please see the Light Duty Steel Shores WITH BEARINGS and Heavy Duty Steel Shores.

*Steel Shores should be attached to a flat solid foundation. Steel Shores should not be subject to any lateral force. Steel Shore should be used to support straight vertical loads only. We recommend tightening set screw in the side of the wing nut with 6mm allen wrench prior to loading. Before construction begins it is recommended that you consult with a certified engineer for approval of our products within your application.
