INCRA Build-It Clamp, $12.95
Compatible with INCRA & Woodpeckers T-Tracks and most brands that use 1/4"-20 hardware, this is ideal if you're looking for a rigid, simple, & cost effective solution. If your clamps are frequently reconfigured and you want super quick setup, use the INCRA Build-It Clamps.

The solid aluminum body is far thicker than similarly-styled clamps for unparalleled stiffness. The large pivot barrel is also captured within the clamp body and can't pop out of alignment - just position the clamp and tighten the knob without having to chase around a loose pivot .

2" clamping range. Made in USA.

Woodpeckers Knuckle Clamp, $23.95
This new model from Woodpeckers incorporates a number of advanced features, and once set up, they're very fast to operate during repetitive work. They're compatible with INCRA & Woodpeckers T-Tracks and most brands that use 1/4"-20 hardware. Made from reinforced polycarbonate, they're virtually indestructible.

The Knuckle Clamp has pivoting, rubber-soled feet to protect your work and evenly distribute pressure. The knuckles molded into the top of the clamp allow repositioning the pivot to the ideal part of the clamp to accommodate changes in the thickness of the material that you're clamping.

The biggest contributors to the clamp's operating speed are the two thumb nuts on the shaft - the lower one keeps the threads vertical and maintains the clamp's position in the T-Track when the clamp is open, and the upper one compresses a spring - loosen the knob, and the clamp body lifts & opens automatically .

2-1/2" clamping range. Made in USA.
