The Dripless ETS2000 Industrial Grade caulking gun has a lightweight composite revolving frame that fits 10 oz. cartridges and has a 12:1 thrust ratio for use with latex, acrylic, and silicone. The revolving frame allows the barrel to rotate for maintaining the same bead orientation when caulking around corners. A spout cutter is built into the side of gun for opening cartridges without a knife, and the hook on the back allows it to hang on a ladder.
