The Newborn 150 Non-Drip Smooth Rod Revolving Frame caulking gun has a steel revolving frame that fits 1/10-gal. cartridges and has a 12:1 thrust ratio for use with low and medium viscosity materials such as latex and silicone. The revolving frame allows the barrel to rotate for maintaining the same bead orientation when caulking around corners. The pressure rod is heat-treated to be longer lasting than standard pressure rods. 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.
