Drip-Free Caulk Guns


Style E	Style G

Minimize mess and waste—when you release the trigger on these guns, the rod retracts slightly to reduce pressure, which stops flow from the sealant cartridge.

Thrust Ratio—To choose a thrust ratio, consider the thickness of the material—thinner materials such as silicone and latex flow easily, so choose a low thrust ratio gun. Thick materials such as urethanes and epoxies require more power to dispense, so choose a high thrust ratio.

Battery-Operated Caulk Guns

Compact Caulk Guns

Unlike standard caulk guns, these guns measure just 4" long and don’t have a cartridge rod, so you can use them in snug spaces and around tight corners. A built-in cartridge cutter lets you shorten caulk cartridges as you work, making these guns even more compact.
