This letterbox is meant to be fitted horizontally. **Q: Hi, I ordered one of these letterbox’s and the brushes are normally on the inside but, the screw heads should be inside and the brushes are outside???** A: Mine went on fine - screws tightened from the inside so can’t be seen or tampered with from the outside, brushes on the outside under the flap. Hasn’t been a problem. Hope that helps. **Q: Is the flap loose, my exist flaps when it's windy, very annoying hope new one doesn't flap with the wind?** A: The flap is spring loaded, never had any problem in strong winds **Q: Is this black on the inside too?** A: Chrome flap on outside and inside of door. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy fit *by D***Y on 29 April 2026* We were very happy with the quality and size of this product, it looks like a quality letter box, it stops the draft blowing in.

Having two people makes it easier because you need three sets of hands to hold everything together which makes it SO much easier and faster to fit . I don’t usually have a lot of luck with DIY projects but definitely don’t be afraid to have a go yourself save yourself some money just make sure you get the correct size measurements are important there are a few different sizes choices and lots of options for the different finishes.Great value for the money a quality item looks great on and is good and sturdy really just have a go ## Frequently Bought Together - Xfort MailPlate 12" Letterplate Matt Black, Premium Draught Proof Postal Letterbox, Telescopic Sleeved Letter Box For uPVC Doors With 20-40mm Door Thickness. - UPVC Door Handles Set - Black - Lever/Lever - 92mm PZ (Centres) - 122mm Screw to Screw - Backplate 212mm X 34mm- Black Replacement- PVC Door Handle --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/390833767-xfort-mailplate-12-letterplate-matt-black-premium-draught-proof-postal](https://www.desertcart.co.th/products/390833767-xfort-mailplate-12-letterplate-matt-black-premium-draught-proof-postal) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-06-08*
