Newborn 290 Elite Series Caulking Gun, 1/10 Gallon Cartridge, 22:1 Thrust Ratio

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.
