Overview

The POWERTEC 71528 is a clamp measuring 11 by 5.5 by 1.6 inches and weighing about 2.8 pounds, sized for securing workpieces on a bench or table rather than for handheld use.

POWERTEC's tool lineup leans toward woodworking and workshop accessories, and this clamp's footprint points to bench or table mounted work holding rather than a small handheld spring clamp. The listing does not specify clamping capacity or throat depth, so buyers should check those measurements against their workpiece before ordering.
