CRL introduces a new caulk gun without the steel rod. Model CRLCG2 includes a patented mechanism that extrudes caulk by exerting pressure on the plastic cap at the end of the tube from a pre-tensioned spring in a lightweight 13.5-inch cartridge gun.
Like a tape measure, the spring-loaded mechanism is located at the handle of the caulking gun, retracting back into itself when the caulk tube is removed so that it’s ready for a new caulk tube to be inserted.
