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.
