    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.

    Spoked Housing

    Pull a chain (sold separately) to manually open roll-up doors. All of these chain wheels have a machinable hub so you can mill the exact bore size you need.
    Iron—Iron hand wheels are durable.
    Aluminum—Aluminum hand wheels have mild corrosion resistance, are lightweight, and are nonmagnetic.
    Required Chain—The chain listed is designed for use with these chain wheels—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.
