North Shore Commercial Door now has the Gatheron GTR-3-390 three channel Remote Control in stock and ready to ship out! This compact transmitter has three buttons, and can control up to three different garage doors or gates. This particular remote control is a visor style unit that comes with a clip. The best thing about this remote is the compact size. The GTR-3-390 measures 1 3/4” tall X 3 1/4” wide X 1/2” deep, making it smaller than a pack of cards.
The GTR-3-390 is a Security Plus compatible remote control. This means that it will work with transmitters from Chamberlain, LiftMaster, Sears Craftsman, Raynor, and other private label controls using a Red Learn Button and 390Mhz. The rolling code technology changes the signal that activates the door on each press of the button, helping to keep your garage and your family safe.
