- First decide where you want to put your letterbox on the door. Use the letterbox as a template and draw around it, you can position it correctly by measuring from the top of the rail (it is being fitted in) to the top of the letterbox.
- If you are a perfectionist you can make sure that the letterbox is positioned both vertically and horizontally by using a spirit level. Make sure you also take note of the spring mechanism (if there is one) and mark this opening on the door.
- Cut out the wasted wood by using a jigsaw or padsaw.
- To help start this off, drill small holes at opposite corners of the template drawing. Remember to use a timber block on the opposite side of the door and at the position where the drill will appear to prevent the door splintering.
- Mark where the fixing bolts will be positioned. Some letter plates such as the Flapmaster type we sell are screw fixed rather than bolt fixed.
- Drill the holes for the fixing bolts.
- Hold a small block of wood on the other side of the door in the same space you are drilling, this will prevent the wood from splintering when the bit passes through.
- Sand any rough edges of the newly cut apertures.
- Fix the bolts in position with the fixing nuts - you may need to cut the bolts down at the back if they protrude past the nut. This can be done with a hacksaw.
