If the slate front is to be recessed into the wall the cut an 18mm border around the letterbox hole. The depth of the border should be the depth of required recess amount + 3mm. I.e. if the slate is to be recessed back 10mm then the border should be chased to a depth of 13mm. |

Step 2 Cut a hole in the rear wall the size shown below.
Note The bottom of the rear cutout should be level with the bottom of the front cutout. The sides should be equidistant in from the front cutout. |
Step 3 Disassemble the containing box by undoing the 4 brass T Nuts with the 4mm Allan key. Remove any threaded rods that remain fixed to the front casting and re-attach the brass T Nuts. Ensure the nylon washers remain on the threaded rods. |

Step 4 On the back face of the slate front, apply a bead of glue suitable for exterior use. (such as No More Nails) 10mm from the. Also apply glue to the front of the containing box. |

Step 5 Align the slate front with the front of the containg box and push the faces together. Use the four 50mm bolts, washers and nylocs to fix the faces together. Note: DO NOT OVERTIGHTEN THE BOLTS as this may damage the slate.

Step 4 Ensure that the slate front is square to the brickwork. (It may be necsessary to loosen the nylocks and adjust the front before re-tightening the nylocs Apply a support until the glue has set. To seal the slate face, run a bead of clear silicon around the sides and top edges (not the bottom) between the slate and the face of the brickwork. Also seal the top and sides between the brickwork and the letterbox sleeve on the back wall.
