Frequently Asked Questions About Garage Door Parts Names

1. What are the main garage door parts names I should know?
The most important are panels, tracks, rollers, hinges, springs, lift cables, cable drums, brackets, seals, and the automatic opener.

2. What is the part that holds the garage door up?
On many doors, torsion or extension springs provide the counterbalance that helps support the door’s weight during opening.

3. What are the wheels on a garage door called?
They are called rollers. Rollers travel inside the tracks and help the door move along its designed path.

4. What are the metal rails on a garage door called?
They are called tracks. Most sectional doors use vertical and horizontal track sections connected by a curved transition.

5. What is the cable on the side of a garage door called?
It is generally called a lift cable. It works with the spring and cable drum system to help raise and lower the door.

6. What is the bar above a garage door spring called?
It is commonly called the torsion shaft or torsion tube. Torsion springs are mounted around or alongside this shaft depending on the design.

7. Which garage door parts are dangerous to repair?
Torsion springs, extension springs, lift cables, cable drums, and bottom brackets can involve significant stored or transferred force. Professional service is recommended for repairs involving these components.

8. How can I identify the correct replacement garage door part?
