Newborn 189D Caulking Gun with 6:1 Thrust Ratio

The Newborn 189D Drip-Free Super Ratchet Rod Cradle caulking gun is designed with a steel half-barrel frame to accommodate 1/10-gal. cartridges and has a 6:1 thrust ratio, making it ideal for use with medium viscosity materials like silicone. The ratchet-style pressure rod features teeth that securely hold the rod in place after each trigger pull, reducing the likelihood of drips, particularly with thinner materials. Additionally, the rod retracts after each trigger pull, alleviating pressure from the tube and further minimizing dripping. The gun also includes a welded plate in the back to secure the cartridge in place, along with a hook for hanging on a ladder. For added convenience, a seal puncture tool and spout cutter are built into the side of the gun for effortlessly opening cartridges without the need for a separate knife.

Caulking guns, also known as caulk or cartridge guns, are used to dispense controlled amounts of products such as caulk, sealants, and adhesives from a tube or cartridge. A manual caulking gun typically consists of a frame that holds the tube, a trigger, and a rod that dispenses the product when the trigger is depressed. The thrust ratio of a manual caulking gun determines how easily the caulk, sealant, or adhesive can be dispensed, with a higher thrust ratio making it easier. Alternatively, air-powered or pneumatic caulking guns utilize a frame and trigger, but rely on an air pressure regulator to push the product from the tube using air pressure instead of a rod.

The steel half-barrel (or cradle) frame of the caulking gun is specifically designed for 1/10-gal. cartridges and offers a 6:1 thrust ratio for medium viscosity materials. The ratchet-style pressure rod provides added convenience by securely holding the rod in place after each trigger pull, reducing drips, while the retraction of the rod after use further helps prevent dripping. With a welded plate in the back to secure the cartridge and a built-in hook for hanging, this caulking gun offers both practicality and efficiency. Additionally, the inclusion of a seal puncture tool and spout cutter on the side of the gun ensures easy cartridge opening without the need for extra tools.
