Fab Fix Nu Mail Heavy Duty 12" Inch Sprung Letter Box Plate for UPVC & Wooden Doors

Premium Heavy-Duty Letterbox Set

This high-quality, heavy-duty letterbox set is one of the best we've come across! Its innovative design features unique anti-snap flaps that open a full 180° both internally and externally. Since the flaps sit flush against the door and open completely, they are protected from accidental damage—whether caused by an enthusiastic postman or a curious child.

Crafted entirely from metal, this stylish letterplate boasts colour-matching flaps and surround. Both flaps are fully sprung with durable stainless steel springs, ensuring smooth operation. The deluxe model also features full internal and external weather sealing, keeping your home draft-free. While it may cost a little more, its superior quality makes it well worth the investment.

For enhanced security, the letterbox can be installed using the supplied blind bolts, which fasten from the inside, preventing removal from the outside. Alternatively, it can be fixed with traditional screw fixings.
