Overview

The Yost LV-4 is a clamp weighing 9 pounds with an 11 by 7.5 by 11 inch footprint, considerably heavier and bulkier than typical bar or spring clamps.

At 4.6 stars across 10,723 reviews, it carries Yost's reputation for shop grade metal tools. The near cubic 11 by 7.5 by 11 inch dimensions and 9 pound weight point to a bench mounted or heavy duty holding tool rather than a lightweight hand clamp.
