This accessory takes the struggle out of clamping tapered workpieces. It effectively adds an articulated face to a vise or clamp jaw – the dome on one side lets its face pivot to match the taper of the workpiece, applying clamping force evenly to simple or compound tapers.
The 3 3/8" × 1 7/8" face has a crosshatched pattern for grip and a groove to center it on convex surfaces. Projection is about 1 5/8".
Made in USA from durable glass-filled nylon and zinc-plated steel.
