The Gibraltar Mailboxes MS00RC03 and the Brass Accents Mail Slot are both modern-looking options that are made from brass, but are available in a range of metallic finishes, and have a matching frame for the inside. Similarly, the CR Laurence No-Draft is basic to look at, however, it includes a flap on the inside, and has two internal brushes, as added protection against the cold weather.

The Skandh Aluminium is a simple, no-frills option with a plain fronted, spring-loaded flap. Modern designs are available in a variety of shapes, styles, and finishes that are sure to match your existing hardware and complement your style of door.īrass, iron, and aluminum are the most common materials for mail slots, due to their weather-resistant and anti-corrosive properties.
