The clamp vise combines a 3 in bench clamp with an anodized-aluminum plate that mounts to the edge of a benchtop to create a simple, highly effective bench vise. It's great for clamping pieces on edge, supported by adjustable clamp blocks and for holding large pieces on top of a bench like a traditional end vise using a pair of included bench dogs. Thanks to Automaxx® auto-adjust technology, the bench clamp adjusts to match the material automatically with a simple squeeze of the handles whether the material is thick, thin or in between. The clamp allows easy regulation of clamping pressure with a simple thumbscrew.
