Instead of pulling a chain or handle to open your steel roll-up 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 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 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 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 overhead doors.
