About this letterbox draught excluders & catchers
A brush on its own seals the sides of the post as it falls through. A flap on its own seals the opening between deliveries. This Stormguard cover has both, so it stops cold air moving in either direction, and it closes automatically after each delivery.
It is made from aluminium and plastic in a silver finish, which resists corrosion and suits stainless or chrome door furniture. The listing says you can fit it inside or outside, which is useful if your door is thin or if you cannot reach the inside of the letterbox.
It fixes with screws, and no drilling of large holes is needed. Because the cover is designed as a replacement for a worn letterplate or as an addition to a plain one, check the dimensions against your door opening on the product photos before you buy.

The complete guide
A flap closes the opening. A brush seals around the post as it passes and when it is not in use.
A flap with a brush gives a layered seal. If one wears out, the other still works.
Check the brush every winter. Bristles that have flattened or split need replacing.
