Frequently Asked Questions:

Will this letterbox fit my existing door aperture?
The internal sleeve requires a minimum aperture of 262mm x 45mm. Most standard letterbox apertures are compatible, and minor adjustments can be made with a hacksaw if needed. This letterbox is available in two door thickness options: 20-40mm and 40-80mm - please select the correct option for your door during checkout.

How do the anti-snap flaps work?
Both internal and external flaps open to a full 180°, sitting completely flush against the door surface. This prevents the flaps from being caught and snapped off during rough handling, unlike standard letterboxes that only open to 90°.

Can this be installed on composite doors?
Yes, this letterbox is specifically designed for uPVC, composite, and timber doors. The included security bolts and gasket ensure proper sealing regardless of door material.

What makes this more secure than standard letterboxes?
The included blind security bolts fasten from the inside of the door, making it impossible to remove the letterbox from outside. The solid die-cast construction also resists tampering better than plastic alternatives.

Will this help reduce draughts through my door?
Absolutely. The dual weather sealing system includes external foam seals and internal draught brushes, creating a complete barrier that eliminates cold air infiltration and helps reduce heating costs.
