Kentbridge Extreme Pro Caulking Gun Comfortable and extremely stable heavy-duty caulking gun with high pressure and high feed rate per press. Handle with a soft, rounded, ergonomic design made of cast aluminum for minimal strain and optimal feel and power. Stepless, long, and smooth feed without “jerking” the feed rod. Equipped with both an anti-drip function—where pressure on the cartridge is released when you let go of the handle, preventing spills—and a thumb button that instantly releases pressure on the cartridge. Fully rotatable cradle. The more robust mechanism, gear ratio, and handle make the caulking gun suitable for use with slower-curing and thicker compounds such as P/U adhesive and MS Polymer, as well as in colder weather. Designed for cartridges containing sealants, adhesives, silicone, etc. Gear ratio 12:1. Maximum pressure force 250 kg. Length per press: 7 mm.
