The Genie 6170H-B is basically the same wall-mount operator as the 6070H but with built-in Wi-Fi and battery backup added. Handles doors up to 850 pounds, doors up to 14 feet high and 18 feet wide. Works with high lift up to 84 inches, full vertical, and low headroom inside hookup setups. This battery backup means the door still works during a power outage, which matters if you've only got one way in and out. Good fit for heavier residential doors or light commercial applications where you need smart connectivity and backup power.
