Dripless BL7500 Industrial Grade Aluminum Barrel Bulk Caulking Gun, 30 oz. Cartridge Capacity, 18:1 Thrust Ratio

The Dripless BL7500 Industrial Grade Bulk caulking gun has an aluminum barrel that can accommodate 30 oz. of bulk caulk and has an 18:1 thrust ratio for use with silicone, latex, drywall, sub-floor adhesives, and polyurethanes. The anodized aluminum barrel is lightweight and provides corrosion resistance. The front cap can be removed easily, and a load-dispense switch facilitates loading the barrel with caulk. The handle has an ergonomic design that reduces hand and arm fatigue. The caulking gun includes six disposable 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.

Dripless, Inc. manufactures caulking guns and caulking and painting accessories. The company, founded in 1992, is headquartered in Santa Rosa, CA.
