I Am the Jaw. The Matthews Matthellini Clamp with 3-inch Center Jaw gives you a strong, solid grip on round, square, or rectangular tubes, and it also works with a range of other common and uncommon tubing shapes. Its fixed jaw is mounted at the base of the Baby Pin portion of the shaft to provide the strongest possible support for the pin. The jaw also has a textured rubber lining to keep it from slipping and damaging surfaces.

Built to Last. A large ergonomic handle turns quickly and easily while giving you plenty of leverage when securing and releasing the clamp. The clamp’s shaft is constructed of 1010 chrome-plated steel, which is stronger than stainless steel.
