The C-Ring Closure Tool administers 3/4” (19.1mm), 15-gauge (.072in, 1.8mm) closures. This tool weighs only 2.8 lbs. and, along with the ergonomic design and balance, reduces wrist strain. The over-molded grip provides maximum user comfort. A simple “no adjustment” valve has fewer parts and requires less maintenance than similar C-ring tools. Our state-of-the-art magnesium- and glass-filled nylon components offer a lightweight and durable solution.
