Built-In Mail Slots Size & OEM Support

Built-in mail slots are often used in different door thicknesses, wall structures, and mailbox designs, so standard sizes may not always fit the project.

We can support custom dimensions based on your drawings, samples, installation photos, or required opening size. OEM support includes material selection, surface finish, flap structure, fixing method, logo marking, packaging, and carton labeling.

For large projects, we can help confirm the mail opening size, screw hole position, plate thickness, and production tolerance before mass production.

Project Case : Built-In Mail Slots

A mailbox brand needed a built-in mail slot for a wall-mounted letterbox system. Their main problem was that the previous flap felt loose after repeated use, and the black coating was easily scratched during assembly.

We adjusted the flap structure, improved the powder coating process, and supplied protective packaging for each piece. After sample approval, the customer used the mail slot as a standard component in their mailbox product line.
