    Can I convert a standard garage door to a high –lift?

    Standard garage doors can typically be converted to high-lift if there is

    enough head clearance in the garage. Head clearance is the distance

    from the top of the garage door opening to the ceiling in the garage.

    Typically 12 inches of clearance from the ceiling is needed for any

    garage door.

    If the ceiling in your garage is 10 feet tall you can use a high lift door to

    raise the door in the open position to 9 feet. The 12 inches of clearance

    from the ceiling is needed to install the spring bar, springs, drums and

    end bearing plates. This example would provide two additional feet of

    clearance for a 7 foot tall garage door.

    High-lift doors are beneficial if the additional height in the garage is

    needed for taller objects. Many times people want to install a lift in

    their garage to allow for two cars to be parked in the same space with

    one on a lift and the other parked under the lift.

    When changing from a standard lift to a high-lift, much of the hardware

    will need to be changed. A high-lift door will require new tracks, drums,

    cables and springs because the geometry of the door has changed. The

    amount of high-lift available is determined by the ceiling height of the

    garage and the distance from the top of the garage door opening to the

    ceiling.

    When changing to a high-lift system the opener will also need to be

    changed to a jack shaft opener. A jack shaft opener takes away the

    need for the opener rail and moves the motor to the side of the garage

    door. A jack shaft opener opens the garage using the spring bar rather

    than a rail with a belt, chain or screw suspended from the ceiling in the

    garage. This clears additional head room needed in a high-lift

    application.

    In some application the high-lift can be closer to the ceiling than the

    recommended 12 inches, but that is on a case by case basis. Not all

    high-lift doors can be any closer to the ceiling than 12 inches.

    High-lift conversion are best done by a garage door professional with

    the knowledge and skill set needed to perform the conversion. Many

    calculations must be made to determine the correct drums, cable

    lengths, springs and tracks needed to perform the conversion.
