How much headroom is required above the garage door?
In order to install torsion-spring hardware, we recommend a clearance of 12 in. (305 mm). On the other hand, if there is only 5 in. (127mm) to 12 in. (304 mm) available, it is best to use a dual-track system, designed for low headroom. When equipping a garage door with an electric door opener, add 2 in. (51 mm) to these measurements.
Torsion (1) | Extension (2) |
Headroom | Operation type | Headroom | Operation type |
| 0" to 5" | Not possible (lower headboard of door) | 0" to 5" | Not possible (lower headboard of door) |
| 5" to 12" | Low Headroom (double track system) | 5" to 8 1/2" | Low Headroom (double track system) |
| 12" and higher | Standard (12" radius) (3) | 8 1/2" and higher | Standard (10" radius) |
- Garaga recommends the use of torsion springs for improved door operation and increased safety.
- Garaga recommends the use of safety cables with extension springs for more security.
- You can order a 15 inch radius with torsion springs operation.
If an electric operator is being used, add 2 inches(51mm) to headroom required.
