Instead of pulling a chain or handle to open your steel roll-up garage door, push a button. These openers come with everything you need to convert your manual door into an automatic one. Simply slide them over your garage door’s drum axle. For smooth operation, they start and stop slowly to prevent the door from lurching and slamming to the ground. Similar to an automatic garage door, they’ll stop and reverse the door if the light beam sensing switch detects an obstruction in its path. Turn on the safety mode to lock the garage door and limit control to a single master remote. If there's a power failure, disengage these openers to manually open the door.

These openers fit most steel roll-up garage doors, also known as rolling sheet doors, with 9 _1/2" or 12" door drums. You can mount them on either side of the door. Do not use these openers with sectional or fabric garage doors.

Also known as jackshafts, these openers will stop and reverse the garage door's downward motion if it encounters an obstruction or the light beam between the opener's sensing switches is interrupted. During a power failure, use the manual chain hoist to move the door. These openers meet UL 325 safety standards for door operators and systems.

Reset fire panels, or open electromagnetic locks, electric strikes, and automatic door openers. These switches require a key to turn circuits on or off, limiting access and preventing accidental activation. The lock is not included; use a 1 _1/4" long mortise lock with a standard cam.
