Measure the opening, fixing centres, overall plate size and door thickness.
Letter Plates and Post Boxes for Secure Mail Delivery
Mail delivery needs a clear opening without turning the entrance into a route for draughts or rain. MacBlair stocks letter plates and post boxes for suitable doors, walls and entrance areas.
Check aperture size, door thickness, fixing centres and weather exposure. A flap, brushes or internal cover can improve closure, while a separate box avoids cutting the door leaf.
Measure twice before forming an opening and keep clear of locks, rails and glazing. Never alter a fire-rated door unless the exact letter plate is permitted by its certification. Check the wider door furniture range for compatible parts, and match the fixing arrangement with suitable door hinges where the installation requires them.
Letter Plates and Boxes FAQ's
Only use a tested, compatible fire-rated product installed exactly as the doorset evidence requires.
Choose a well-fitting model with suitable flaps, brushes or an internal cover.
A separate box avoids altering the leaf and may suit doors where cutting is restricted.
Choose a material and finish rated for the weather exposure and maintain it as instructed.
