- Single door overhead gear combines compactness with simplicity.
- Overhead gear should be fitted either to a weather beaded 70mm x 70mm (2.3/4" x 2.4/4") standard timber goal post frame (not supplied) or a Wessex steel frame. Frame dimensions: 54mm(2 1/8") wide on side section.
- The minimum headroom required above the lower face of the frame head is 48mm (1 7/8")
NOTES
- In use, the lifting gear reduces drive through heights by 91mm (3.58") although there is no reductions in the width.
- For back fixed frames allow the frame to overlap into the aperture by 13mm (1/2") on both sides to allow for coursing and tolerances.
FITTING FRAMES TO THE BRICKWORK
- Frames may be fitted within or behind the brickwork as per the drawings shown. Fitting behind the brickwork, if the garage length allows, will increase the drive-through width.
- A weather bead should always be fitted to the under-side of the door frame lintel in front of the door to hide the top gap. This feature is integral on the Wessex steel frame.
