Newborn 424 Bulk Sausage Ratchet-Rod Caulk Gun, for Use With a 10-Ounce or 20-Ounce Sausage

This Newborn 424 ratchet-rod caulking gun fits a 10-ounce or 20-ounce sausage pack or 24-ounces of bulk caulk. This gun has a thrust ratio of 6:1 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. A spout cutter is built into the side of the gun for opening cartridges without a knife, and a wrist strap allows the gun to be held securely. The caulking gun includes one dual hytrel cup for use with bulk caulk or sausage packs, one ring cap for attaching nozzles, three plastic cone nozzles, and one 1/2"-diameter metal nozzle.
