The DeWalt® 18-Volt caulking gun delivers the power speed and control needed by an Auto Glass Technician while using the same battery as your 18-Volt Equalizer® Express® or any DeWalt® 18-Volt tool. This caulking gun has a powerful pushing force of 650 pounds that dispenses the highest viscosity materials with ease. Its combination of a variable speed dial and trigger switch allows perfect control when laying a bead of urethane. Use the dial to set a specific speed or turn it all the way up and use the trigger to control the speed. The tools auto-reverse feature prevents unwanted dripping of materials and also has a built in lock switch to prevent accidental startups.
