Overhead Door Openers
Pull a chain (sold separately) to manually open overhead doors. All of these openers have a machinable hub so you can mill the exact bore size you need.
The chain listed is designed for use with these openers—do not substitute other chain. The chain that's not rated with a capacity is for opening, but not supporting, the weight of a door—use it on doors that have independent supports.

Automatic Overhead Door Openers
Also known as jackshafts, these openers operate 24-ga. or thinner overhead doors. The opener will stop and reverse the door's downward motion if it encounters an obstruction when closing or the light beam between the opener's light beam sensing switches is interrupted. During a power failure, use the manual chain hoist to move the door. All of these openers meet UL 325 safety standards for door operators and systems.
When facing the side of the door with the opener, a right-side mount opener is located on the right side of the door, left-side mount is on the left. An optional remote transmitter is sold separately.
