Garage door anatomy and terminology
There are over 65 individual structural and operational components in a modern garage door that work together to make your garage door function properly. Let’s take a look at some of the basic garage door parts.
Sections: A group of panels – most common a steel on sectional door design – reinforced with tiles interconnected with hinges and rollers. You can replace a section without having to replace an entire door.
Track: Guides a section to raise or lower a garage door. Garage door tracks are on both sides, and there are two sets of tracks: vertical and horizontal. The curved part of the track is referred to as the radius.
Rollers: The rollers are connected to the tracks, they guide your door when it opens and closes. Together, tracks and rollers allow a garage door to move up and down.
Top brackets: Structured supports in the upper part of a garage door that provide for attachment of lifting cables. The brackets along with the hinges hold a garage door together. Anytime they get loose or damaged; they need to be replaced.
Bottom brackets: Fixed supports at the bottom of a garage door that provide for attachments of lifting cables.
Hinges: Attach and provide support for sections of garage doors. These allow the garage door to roll up or down.
Cable drums: Grooved drums on the torsion spring shaft that allow lifting cables to wind when garage doors open. Along with the cables, they work hand in hand with the springs to keep your garage door balanced as it opens and closes.
Torsion springs: Does the heavy lifting; it raises and lowers garage doors via cable winding on drums.
Extension springs: They are made to stretch or extend when there is a force applied. Extend along both horizontal tracks to assist in raising and lowering the garage door.
Operator hanger: Hold together the horizontal track to the ceiling for added support.
Emergency pull cord: When pulled, the motor is disengaged and allows the garage door to be lowered or raised manually.
Electric operator: Enables the garage door to be raised or lowered mechanically.
Operator rail: Garage doors generally either have a chain, belt, or screw drive.
Rear track hanger: Links the horizontal track to the ceiling for added support.
Bearing plate: Joins to the header to support the spring and shaft.
Sensor: 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.
