| Track | Headroom required |
|---|---|
| 3" Front | 8.5" |
| 6" Front | 11" |
| 3" Rear | 4.5" |
| 6" Rear | 6.5" |

Recommended Framing & Wiring Detail
Framing
- 2" × 6" jambs on both sides, running up past the header to the finished ceiling.
- 2" × 4" header across the top of the opening, jamb to jamb.
- 2" × 12" center pad on the header, up to the finished ceiling.
- Finished opening height = door height.
- Finished opening width = door width − 2".
Trolley Operator Wiring
- Outlet at door height + 3', 12" off center.
- 2-strand low voltage from each photo eye to the operator.
- Wall button: commercial requires 4-strand wire, residential requires 2-strand wire.
Jackshaft Operator Wiring
- Operator and outlet at the side of the opening.
- 2-strand low voltage from each photo eye to the operator.
- Wall button: commercial requires 4-strand wire, residential requires 2-strand wire.
Wiring
Make sure to prewire for safety sensors and the wall button if we will be installing doors after walls and ceiling are finished. Otherwise, wiring will be surface mounted.
Weather Seal
We recommend matching the door seal to the jamb color on woodgrain doors.
If jambs are not finished at the time of install and we have to return to install weather seal, there will be an additional charge.
How Much Space We Need to Install Your Door
Please provide our installers with adequate room to work.
Install Toward the End of Your Project
We recommend installing your door toward the end of your project.
Below are common issues we find when doors are installed prematurely or before ceilings and walls are finished:
- 01Dented sections due to tradesmen.
- 02Drywallers removing backdrops and not putting them back in the correct spot.
- 03Drywall dust gets in rollers, bearings and hinges, causing wear and noisy operation of the door and operator.
- 04Drywall dust and mud get on the door. Have drywallers cover the door, track and springs prior to finishing drywall.
Delivery
Doors will be delivered prior to installation. Please do not stack material on sections or use them as a work bench.
