Professional compact caulk gun. Brings all the features of the classic Siligun to the professional end user. Includes a strong, yet lightweight aluminum body frame, and is made to work in the toughest scenarios. At just 4 inches, it is no bigger than the tube of caulk it is dispensing. Cut off the excess tubing to reach even tighter spaces. No more oversized, heavy caulk guns that limit your reach. When you release the trigger, the flow stops. No more run-on mess that traditional caulk guns leave. Features a powerful 24:1 thrust ratio and is suitable to work with any 10-ounce tube (310 ml) on the market.
