Letterboxes

UPVC Door Letterboxes

An exact replacement letterbox may no longer be available, but a similar one can often be used.

The most important factor when choosing a replacement letterbox for a upvc door is checking the hole originally cut in the door is covered by the new letterbox. In some cases the hole in the door may need enlarging and new screw holes making.
