Overhead Door Openers
Solid Housing
Spoked Housing
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.
