COX 10 oz. PNEUMATIC CAULKING GUN PN# 63001 – Fits 10 oz. cartridge. Cox’s new Series 3 guns are ergonomically designed. Its new lightweight, lightly textured handle and well balanced barrel make Series 3 a pleasure to hold and use. This is of particular importance for operators who use the applicator above shoulder height or repeatedly during the day. The Series 3 is ideal for environments where production lines and refinishing operations take place. To aid productivity and improve operator comfort when used indoors Series 3 is fitted with a built-in silencer which lowers the noise level of the applicator to less than 70dB. Located conveniently on the front of the handle, the all new easy-to-use regulator provides operators with fingertip control of the airflow through the barrel. As a result, Series 3 can effortlessly dispense a wide range of low to heavy viscosity sealants contained in the cartridge.
