Newborn 125 Smooth Hex Rod Parallel Frame Caulking Gun, 1/4 Gallon Cartridge, 10:1 Thrust Ratio

The Newborn 125 Smooth Hex Rod Parallel Frame caulking gun has a steel skeleton frame that fits 1/4-gal. cartridges and has a 10:1 thrust ratio for use with medium viscosity materials such as silicone. The smooth pressure rod requires less force and is quieter than a ratchet-style pressure rod. 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.

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.
