The Husky Heavy-Duty High-Leverage Caulk Gun is designed for use with standard 10 oz. cartridges and delivers professional performance for applying caulk, sealants, and construction adhesives. An adjustable thrust ratio lets you match dispensing force to the material being used, while a selectable Drip/Drip-Free mode provides greater control during application. The rotating barrel makes it easier to maintain a consistent bead around corners and tight spaces, and the cushioned trigger helps reduce hand fatigue during extended use. A built-in seal punch tool is conveniently located near the trigger for opening cartridge seals. The rounded skeleton frame allows for quick cartridge loading and removal. Backed by Husky's Lifetime Warranty.
