Newborn 301 Smooth Hex Rod Cradle Caulking Gun, 1/10 Gallon Cartridge, 12:1 Thrust Ratio

The Newborn 301 Smooth Hex Rod Cradle caulking gun has a steel frame that fits 1/10-gal. cartridges and has a 12:1 thrust ratio for use with high viscosity materials such as acrylic, adhesives, asphalt, butyl, and cement. The smooth pressure rod requires less force and is quieter than a ratchet-style pressure rod. The zinc chromate plating offers good corrosion resistance. A seal puncture tool and a spout cutter are built into the side of gun for opening cartridges without a knife, and a wrist strap allows the gun to be held more securely. The hook on the back allows it to hang on a ladder.

Caulking guns, also called caulk or cartridge guns, dispense a controlled flow of products such as caulk, sealants, and adhesives from a tube or cartridge. A manual caulking gun consists of a frame which holds the tube, a trigger, and a rod which moves forward when the trigger is depressed, dispensing the product. Manual caulking guns have a thrust ratio; the higher the thrust ratio, the easier it is to dispense the caulk, sealant, or adhesive. Air-powered or pneumatic caulking guns also have a frame and a trigger, but are used with an air pressure regulator that pushes the product from the tube using air pressure instead of a rod.

Newborn Brothers Company, Inc. manufactures sealant and adhesive dispensers and accessories. The company was founded in 1974 and is headquartered in Jessup, MD.
