Stanley’s new 2×4 bar clamp hardware (STHT83166) attaches to standard 2×4 lumber to create any size clamp you need.
Slide both pieces along a 2×4 beam, hand-tighten the locking foot, and you have an instant clamp that can provide up to 400 pounds of clamping force. Add a few screws to get up to 850 pounds of clamping force at your disposal.
Both clamp components have non-mar pads to help protect work surfaces.
Need a spreader instead of a clamp? No problem, just reverse the direction of the jaws.
The clamp is simple, but ingenious. I’m not ready to throw away my bar clamps or pipe clamps, but can definitely see why a set or two of these clamps would be excellent at construction sites.

The 2×4 clamp is available in the USA and Canada for about $20-25.
