Overview

The POWERTEC 20326 is a clamp measuring 6 by 6 by 3 inches, a compact footprint suited to smaller workpieces and detail clamping rather than large panel glue-ups.

POWERTEC makes woodworking accessories and clamps aimed at hobbyist and small shop use, and the boxy 6 by 6 by 3 inch dimensions suggest a corner or specialty clamp shape rather than a long bar clamp. No further attribute or seller detail is listed, so throat depth and clamping force go unconfirmed.
