Cheap Lee Valley Kreg Right-Angle Auto-Adjust Clamp

This robust all-steel quick-release clamp is adjustable for clamping force, and once set, automatically maintains the same force regardless of stock thickness, so you can switch workpieces without having to make adjustments. The thumbscrew adjuster lets you apply just a light hold for delicate work or up to 400 lb of clamping force at the maximum setting.

With a 5″ throat and 4″ material capacity, this clamp is for perpendicular joins such as with carcass construction. Its swivel pad on one arm and special dowel-like jaw on the other quickly draw joints together, using the pocket-hole recess as a support, while screws are driven in adjacent pocket holes.
