Letterbox Draught Excluder – With Flap


FREE delivery on all UK orders over £50!

Draughts manage to sneak through all sorts of cracks, including through gaps in your letterbox. Our internal letterbox draught seals are just the ticket for stopping those icy winds seep into your front porch.
Simple to fit and easy to use, a letterbox draught excluder acts as a blockade to cold streams of air passing, stopping them in their tracks before they can enter your home through the post box.
The cleverly designed bristles simply brush out of the way any time a letter or parcel is posted through, they then swiftly return to position once the item has fully cleared the letterbox. With this design you’ve got the extra draught protection of a sturdy metal flap, which again just pushes out of the way and returns to place once your package has slipped past.
