The Drip-less Caulking Gun fits 1/4-gal. cartridges and a 12:1 thrust ratio for use with silicone, latex, drywall, sub-floor adhesives, polyurethanes, and concrete masonry and roofing sealants.
On the non-drip setting, the rod retracts after each pull of the trigger, removing pressure from the tube to help prevent dripping.The hook on the back allows it to hang on a ladder.
