About this letterbox draught excluders & catchers
Colour makes a surprising difference on a letterbox cover. White brushes on a dark brown door look like a mistake, while a brown cover reads as part of the door. This Merriway StormSeal is brown PVC, which suits oak-effect, mahogany-effect and stained timber doors.
The listing gives full dimensions: 343 x 80mm outside, a 275 x 43mm aperture and fixing centres of 311 x 51mm. Those are the numbers to compare with your existing letterbox. If your screw holes are the same distance apart, installation is a drop-in job. If not, you can drill new pilot holes.
The double brush design is intended to reduce the air that moves through the opening and keep the post flowing. It is supplied with screws, so a screwdriver is all you need. Choose it if the door is brown or if you simply want a cover that does not stand out.

The complete guide
Fittings on the inside of the door are on view every day. A matching colour makes them disappear.
Brown suits wood and wood-effect. Black suits modern composite doors. White suits painted and uPVC.
Use the existing screw holes where possible. If you drill new ones, make small pilot holes so the timber does not split.
