The Dripless ETS5000 Industrial Grade non-drip caulking gun has a composite revolving frame that fits 1/4-gal. cartridges and a 18:1 thrust ratio for use with silicone, latex, drywall, sub-floor adhesives, polyurethanes, and concrete masonry and roofing sealants. The gun has both drip and non-drip settings; on the non-drip setting, the rod retracts after each pull of the trigger, removing pressure from the tube to help prevent dripping. The revolving frame allows the barrel to rotate for maintaining the same bead orientation when caulking around corners. 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.
