Introducing our patented Auto Shut-Off Technology! The Ultra Series is our top of the line glue gun! We have redesigned our classic glue gun; adding features to help you tackle all of your DIY and home improvement projects. We have upgraded the wattage on all three guns, giving you more glue with every squeeze. Each gun features dual temperature capability. We've redesigned the body of the glue gun to allow you to lay it down while you’re working without worrying about glue back up. This series is equipped with a safety fuse; that shuts the glue gun off in the event of a short. These glue guns also have an insulated nozzle which helps protect against burns. The Auto Shut-Off Technology will shut the glue gun off after 30 minutes of non- use (the timer resets after each squeeze of the trigger). Forgetting to turn off your glue gun is a thing of the past! This unique feature brings the user peace of mind.
