- Classic doors require headroom of 300 mm, and side room of 70 mm or 90 mm.
- Compact doors require 205 mm headroom and 70 mm side room.
- The bottom lath will hang down into the opening, so will reduce the drive through height by 77 mm or 55 mm respectively.
- If the door is installed between the opening the drive through width will be reduced by twice the guide width, and the drive through height will be reduced by the headroom requirement and bottom lath size.
Where will my door fit?
Internal Face Fix
Where there is sufficient side and headroom, the guide rail and roller assembly would be installed directly to the inside of the garage opening. Recommended for most applications.
Installed in between the opening, good where there is limited side or headroom inside the garage. This will reduce the drive through height noticeably.
External Face Fix
Fitted to the external face of the garage, useful where there is not enough space to install on the inside face, but where maximum drive through space is required
