anatomy of garage door  

Here’s the inside look of a sectional door:

1. Torsion Spring
Counterbalances door’s weight so that it can be lifted easily. 

2. Track
Guides door up to ceiling and back.

3. Roller
Rides inside track. Steel ones are noisy; nylon is quieter.

4. Hinge
Connects horizontal sections.

5. Section

6. Lock Bar
Engages with track to prevent door from opening.

7. Weatherstripping
Seals door edges against air infiltration.

Now that you know the basic parts of a garage door,  should something break, be hit or in the case of weatherstripping chewed off by little critters, you will know what to ask for as far as repair is concerned.  Just submit a service request below.
