On the analog side, this unit gives you an industrial-strength 1/2 horsepower motor that produces more than enough lifting power for your single or double garage door. The rugged, chain-drive construction provides superior, long-lasting dependability and toughness. The unit also includes the "Protector System," which automatically reverses the garage door if an obstruction is sensed-you'll see the value of this if you've ever left the tail-end of your car in the path of a descending garage door. A single-button remote control is included, as is as a multi-function wall-mount panel that allows you to control the light and to activate a lock-out feature. Six-year warranty.--Josh Dettweiler
