Best For garage Door: M-D building Products Mail Flap

The m-d building products mail flap is the best reliable flap on the market today. The mail carrier must lift the flap to deliver the mail. It includes flap, back plate, and fasteners. It includes very nice quality and all screws and a template. The higher position makes it more subject to weather but it does appear to seal well enough.

It comes with this installed, all that's visible when peeking through from the outside, is a small patch of garage floor right in front of the slot. The hinge spring has some tension to it. The color is holding even though the door is exposed to harsh direct sunlight. It is great for blocking sightline for security and privacy.

Best For Front Door: CR LAURENCE Mail Flap

Cr Laurence line of flap come in a pretty wide variety of styles, so you can definitely find one that suits your individual preferences and needs. Your standard mail slot is very drafty and they really make no attempt to block the draft, costing you a lot of money in the long run with heating and cooling. It is best for a door with an aspect sheltered from direct wind. The spring loaded flaps close the flap up against a rubber seal and brushes underneath. The rough bristles really blocks the hot/cold air. The doors stay shut even when hung vertically.

There are two indentical pieces, one for the inside, one for the outside. The brush like filter is on each side as well, under the flap. This is the same for both slots that you get so you really get four layers of draft protection.

Anodized aluminum in satin or black
You can use any flap for exterior
Brush strip and draft excluding flap seals
Looks nice, and will last a while
