Introducing our patented Auto Shut-Off Technology! The Ultra Series is our top-of-the-line hot glue gun! We have redesigned our classic hot glue gun; adding features to help you tackle all of your DIY crafts and home improvement projects. We have upgraded the wattage on all three glue guns, giving you more glue with every squeeze of the trigger. Each hot glue gun features dual temperature capability, side fins that allow you to lay them down safely while in use without worrying about glue back up, and all have insulated nozzle covers that help protect against burns. The Auto Shut-Off Technology will shut the glue gun off automatically after 30 minutes of non-use (the internal timer resets after each squeeze of the trigger). Forgetting to turn off your glue gun is a thing of the past! This unique feature along with our internal safety fuse brings the user total peace of mind.
