The Newborn 620-AL aluminum smooth rod caulking gun fits 10 oz. or 20 oz. sausage packs, 24 oz. bulk caulk, or 8-1/2" or 10" cartridges, and has an 18:1 thrust ratio for use with medium to high viscosity materials such as silicone, acrylic, adhesives, asphalt, butyl, and cement. The smooth pressure rod requires less force and is quieter than a ratchet-style pressure rod. The aluminum barrel and zinc alloy handle and trigger are lightweight and provide corrosion resistance. The caulking gun includes a cup for use with sausage packs, a combination dual hytrel cup and conical ejector for use with bulk caulk, and three plastic cone nozzles. 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.What's in the Box?
