Tired of manually dealing with the one you have? or of all the problems with your current device? With our sliding gate opener, your troubles are over. Working with any sliding driveway gate or sliding garage door up to 1800 lb. in weight and 40 ft. in length, this gate opener is a must have for your home. Our gate opener handles even heavy gates at 39 ft. per min. thanks to its powerful 380W motor and ANSI #41 roller chains. With smaller gates, it works just as well and provides an even longer service life.
