⚡ At a Glance
- • Fit & Compatibility: Telescopic depth suits doors 40–80mm and requires 275mm screw hole spacing
- • Best for: Homeowners replacing standard letterbox covers on UPVC, composite or timber doors
- • Not ideal for: Doors outside 40–80mm thickness or with non-standard screw hole spacing
Aluminium letterbox cover measures 305 x 70mm with 275mm screw spacing and telescopic depth for 40–80mm doors. Internal and external flaps open 180 degrees and sealed guards protect mail from dust, pests and rain.
Keeps mail dry - with sealed built-in guards
Sealed guards sit around the aperture so flaps close tightly and block wind-driven rain and dust. Precision construction fills gaps to improve overall sealing against drafts.
Letters and small parcels remain dry and cleaner, reducing the need to dry or repackage mail. Cleaner interior surfaces and fewer pest issues result from the improved seal.
Flexible fit for most doors - with telescopic adjustable depth (40–80mm)
Telescopic design allows the body to extend or retract to match door thickness between 40 and 80mm, while external and internal flaps open 180 degrees to avoid stress on hinges. The unit is intended as a direct replacement when hole spacing matches.
One cover works across a wide range of timber, UPVC and composite doors without extra trimming. Replacement is simpler when existing cut-outs fall within the supported dimensions.
Quick, secure installation - with included fixings and standard 275mm screw spacing
Fixings are supplied for a straightforward fit and the cover requires 275mm spacing between screw holes to complete installation. Accurate hole alignment and included components help the cover sit flush.
Fast fitting cuts installation time and reduces fiddly adjustments. A precise match to common screw patterns means fewer modifications to the door.
