    Garage Door Components:

    (1) Sections: Steel panels reinforced with stiles interconnected with hinges and rollers. You can replace sections without having to replace an entire door.

    (2) Bottom Brackets (AKA Bottom Fixtures): Structured supports at the bottom of a garage door that provide for attachments of lifting cables.

    (3) Cable Drums: Grooved drums on the torsion spring shaft that allow lifting cables to wind when garage doors open.

    (4*) Torsion Springs: Provides the means to raise and lower garage doors via cable winding on drums. 

    (5*) Extension Springs: Extend along both horizontal tracks to assist raising and lowering a garage door.

        Notes Regarding Garage Door SpringsIf a garage door does not open, a damaged spring is the most common problem. Garage Doors will either have torsion springs or extension springs. The above example includes both just as an example. Only attempt to repair or replace garage door springs if you are a trained professional. Springs are the most dangerous component on a garage door. Springs generally last 8-10 years on a residential home.

    (6) Operator Hanger: Attaches the horizontal track to the ceiling for added support.

    (7) Track: Guides a section to raise or lower a garage door. Garage door tracks are on both sides and often referred to as horizontal or vertical tracks. The curved part of the track is referred to as the radius.

    (8) Top Brackets (AKA Top Fixtures): Structured supports at the top of a garage door that provide for attachments of lifting cables.

    (9) Hinges: Attach and provide support for sections of garage doors. These allow the garage door to roll up or down.

    (10) Emergency Pull Cord: When pulled, the motor is disengaged and allows the garage door to be lowered or raised manually.

    (11) Operator (Motor): Enables the garage door to be raised or lowered mechanically.

    (12) Operator Rail: Garage doors generally either have a chain, belt, or screw drive.

    (13) Rear Track Hanger: Attaches the horizontal track to the ceiling for added support.

    (14) Bearing Plate: Attaches to the header to support the spring and shaft.

    (15) Photo Eyes: Detects the presence of an object by using a light transmitter. If the beam is blocked, the garage door will not close. These must be properly aligned for a garage door to operate.
