The ½ HP Chain Drive Garage Door Opener Kit With myQ® is designed for 7 ft. garage doors, and the opener's rugged chain drive will get the job done, day after day. Simple and straightforward installation ensures you'll be using your new garage door in no time. You can easily control your garage door from anywhere at anytime, as well as get real time alerts, all from your smartphone with the myQ® app. And with a wireless keypad, outside access is available with a simple touch. It can be programmed with up to 24 permanent PINs and 24 temporary PINs for limited, single-use access, and comes with an all-weather cover. Plus, the 3-Button remote control allows you to easily program up to three garage doors and boasts a frequency range of up to 1500 ft. The multi-function wall controller can control the garage door opener and its lights separately, and is capable of locking out remote controls from gaining access, which is particularly useful to prevent break-in if remotes are lost or stolen. The included Safety Sensors stop the garage door from closing if something is in its path.
