Soft, yet extremely rigid, polyurethane vise jaws fit comfortably in a 4' or 5' vise and are held in place by embedded magnets. Non-slip surface grips precious firearms firmly without crushing, marring, or scratching. Top “lip” fits the top of your vise jaws adding two inches to allow extra protection and more work area. Surface resists oils and wipes clean. Each set comes with a separate polyurethane cover for vise screws or anvils so you can be absolutely sure that no part of your guns or tools will come in contact with the vise. Channeled soft jaws have all the same features as the Standard version with the addition of machined vertical and horizontal channels with 5⁄8' radius for an improved grip on contoured parts such as barrels and actions. SPECS: Molded polyurethane, red. 5” (12.7cm) wide, 2-1?8' (5.5cm) high, 5?8' (1.6cm) thick.
