Residential Garage Door Openers

Garage door openers that use an operator rail turn a chain or belt. This piece connects to a trolley, which is also called a carriage. The trolley pulls the opener arm to lift the garage door, and pushes the arm to close the door. A piece of rope typically hangs down from the trolley. This is used to disengage and reengage the opener.

When the opener is disengaged, pressing the wall button or the button on your remote will run the opener and turn the belt or chain. It will not, however, open or closed your door.

Hoist style operators include a floor level chain hoist to ease manual operation in an emergency or power outage. The operators are typically mounted to the wall when used with larger sectional overhead doors with vertical or high lift and mounted to the wall or the front of the hood when used with rolling doors and grilles. H operators are attached to the door jackshaft to indirectly drive the door.
