The most distinctive feature of the Speed Rail, Grid Pipe and Scaff Pipe is its telescopic design. Unlike traditional speed rails that must be cut to size, the Grip Rail is extendable. The Grip Rail is multi-functional in mounting, has a junior 1-1/8 "receiver, is compatible with existing grip hardware such as grid clamps , matthellinis and other grip accessories. Multiple grip rails can be paired with a matthews double-sided junior pin (429068). Each Grip Rail comes with a clamp reducer and has an internal stopper that prevents the sections from separating. The grip rail can be locked with grub screws or t-handle, providing a secure and customizable fastening.
