Learn More About Custom Mail Slots

Custom mail slots are designed for projects where appearance, size, and installation details matter. A mail slot is not only a simple opening for letters. It also affects the door’s front appearance, user experience, and long-term durability.

Custom mail slots are suitable for both new product development and replacement product lines. They can be supplied as front plates, complete mail slot sets, inner covers, draft excluder options, or combined door hardware accessories.

Custom Mail Slots Size and OEM Support

Custom mail slots can be developed based on your existing product line, door system, or market demand. If you already have a sample or drawing, we can follow the size and structure. If you only have a target application, we can help review the suitable size, material, finish, and fixing method.

Common customization options include plate size, mail opening size, screw hole position, flap movement, material thickness, surface color, logo, packaging, and accessories.

Custom Mail Slot Project Example

A door hardware distributor needed a custom black mail slot range for modern front doors. Their existing supplier only offered standard sizes, which did not match several door models in their local market.

We helped adjust the front plate size, flap opening, screw hole position, and matte black finish. The products were packed with the customer’s own label and installation screws. After testing the first batch, the customer added more finishes to complete the product line, including brushed stainless steel and antique brass.
