Comes complete with an 11" Articulating arm. The locking control knobs release or increase tension allowing one to find the desired position. This articulating aluminum arm simplifies the mounting and placement of the 1/8" 6"x6" Acylic mirror. The Articulating arm attaches to a galvanized clamp that has a 7/8" jaw opening. This assembly requires no drilling and is the perfect solution to monitor the amount of Brass and Bullets in the collators. Color is red and black. Mfg: Mark 7 Reloading
