This impressive C-Ring Closure Tool has the same features at its big brother, in a 1/2” (12.7mm), 16-gauge (.0625in, 1.59mm) option. The design is lightweight, ergonomic, and balanced to reduce wrist strain and operator fatigue. The simple "no adjustment" valve system has fewer parts and requires less maintenance. It incorporates state-of-the-art magnesium- and glass-filled nylon components for lightweight durability. The over-molded handle grip offers maximum operator comfort.
