The Metal Vertical Magflap™ | MK3 Letterbox Draught Excluder

I waited several years for the Mk3 vertical magflap to be developed and it was well worth the wait. Not only does it fit perfectly and cut out the fierce draught that used to come through our letterbox but it is also more eco friendly ie made of metal and cork rather than plastic and foam. A fantastic product! Delivered efficiently and easy to fit.

Well made. Fast delivery. Very expensive

Had the mk1 version and whilst it worked great at keeping the downstairs smoker’s smell out of our flat, we did have one issue in that the magnet was too strong and caused the postman to quite forcefully shove his letters through the letterbox to overcome the magnet strength. This eventually resulted in the hinge at the top snapping, the mag flap fell to the floor and the magnets broke off.

I personally feel the magnets are way too strong and only needs something just enough to hold it closed rather than it being so firmly held shut. I’m about to try out the mk3, so hopefully either that has been addressed or the hinge is stronger to deal with the poor frustrated forceful postie!
