Where to buy
Before you frame anything
Rough opening and clearances
For a sectional door the rough opening equals the door size exactly. A 16x7 door needs a 16'0" wide by 7'0" high finished opening.
| Clearance | Minimum | Why |
|---|---|---|
| Headroom, standard torsion | 12" | Between the top of the opening and the ceiling. |
| Headroom, low-clearance kit | 4.5" | Costs more and needs a different spring assembly. |
| Sideroom, each side | 3.75" | For the vertical track. 5.5" if the opener rail is side-mounted. |
| Backroom | door height + 18" | Add another 24" for a ceiling-mounted opener. |
