Fitting Guide
Tools: a tape measure, the correct hand screwdriver, a small spirit level, a door wedge and a soft cloth.
Before you start
This panel model is specified for 20–35 mm doors or panels, with a 314 × 70 mm face and 270 mm fixing centres. Measure the panel, routed opening and fixing positions separately. Use this panel model’s side-view drawing: the face dimensions describe the cover rather than the required opening.
Fit and check
- Hold the door open with a wedge. Support the outside letterplate while you undo the existing inside fixing screws, then remove both halves without damaging the edge of the opening.
- Measure the door thickness, existing routed opening and fixing centres. Dry-fit the new halves and check that the sleeves and fixing positions meet without force. The face size is the cover size, not the cut-out size.
- Fit the outside and inside halves in the orientation shown in the supplied instructions. Start both fixing screws by hand and tighten evenly, keeping the faces level and flat against the door. Use the specified fixings and adjustment method for this model.
- Open each flap fully and check that it returns freely, that nothing catches inside the opening and that post passes through without snagging. Recheck the fixings after the first operation.
For a new cut-out, use the exact panel-model template and check the door maker’s permitted preparation before cutting. The standard deeper letterplate drawing is not a substitute.
