Overview

The POWERTEC 71409 is a clamp weighing 0.61 kilograms with dimensions of 9 by 4.5 by 1.2 inches. Those measurements point to a compact clamp sized for light to medium duty holding.

POWERTEC's clamp line covers a range of styles from bar to spring clamps, and this listing does not name the exact style beyond weight and size. At around 1.3 pounds, it is light enough to handle in multiples for a glue-up without weighing down the workpiece.
