Abstract: Shown is a clamping system with multiple clamps that work in combination with each other to support a load attached to an open web joist. This clamping system is typically used to clamp a piping system, of the type commonly used to suspend a basketball backboard and basket, to an open web steel joist of a gymnasium. The clamp combines a prior art “horizontal” clamp subassembly, which clamps to the opposed “lips” of the open web joist, with a second clamp subassembly which provides a “vertical” clamp centered within the horizontal clamp, supported above the open top portion of the open web joist and extending through the open middle portion of the open web joist.
