The GU4TG-R is a universal 4-button remote control designed to operate up to four garage door openers or gate receivers from multiple brands on a single device. It supports both rolling code and DIP switch technologies, making it compatible with most garage door openers and gate receivers produced after 1993 with functional safety sensor systems. The remote comes pre-programmed for popular manufacturers and allows easy reprogramming to your desired button layout. Its compact, key fob-sized design fits easily in pockets, purses, and backpacks. The rubberized grip edge provides secure handling. Each unit includes both a visor clip and keychain attachment, so you can choose your preferred carrying method. An LED light assists with quick and easy programming.
