Newborn 217D Drip-Free Super Ratchet Rod Cradle Caulking Gun, 1/4 Gallon Cartridge, 6:1 Thrust Ratio

The Newborn 217D Drip-Free Super Ratchet Rod Cradle caulking gun has a steel half-barrel frame that fits 1/4-gal. cartridges and has a 6:1 thrust ratio for use with medium viscosity materials such as silicone. The ratchet-style pressure rod has teeth that hold the rod in place after each pull of the trigger. For thinner materials, this helps minimize drips. The rod retracts after each pull of the trigger, removing pressure from the tube, which also helps prevent dripping. There is a welded plate in the back for securing the cartridge in place. The hook on the back allows it to hang on a ladder, and a seal puncture tool and a spout cutter are built into the side of the gun for opening cartridges without a knife.
