The C1502 Post V-Clamp Mount is designed specifically for fastening cylindrical objects such as HeNe Lasers to our rigid Ø1.5" Posts. The C1502 will accept cylindrical objects ranging in diameters from Ø0.56" to Ø2". Each unit comes with one clamping arm (PM4); extra arms can be purchased separately. The v-clamp can be manually adjusted within a ±10 degree range and then locked in place with two 8-32 socket head cap screws. Vertical positioning is achieved by sliding the rear clamping mechanism along the length of the Ø1.5" post. Once the desired vertical position is achieved, the clamping mechanism is actuated with a 3/16" Allen key or balldriver.
