Mail Slots

Need mail delivery through a door or wall instead of a curbside box? Our stainless steel mail slots handle both setups. The manufacturer builds each unit from stainless steel with a brushed, metallic finish, and every slot ships with the hardware required for installation.

We sell front plates, rear plates, and complete front-and-rear sets, so you can order replacement parts for existing installations or full kits for new builds.

Through-Door Mail Slots

Our through-door mail slots install directly into interior or exterior doors, allowing mail carriers to deliver through the door without a separate mailbox.

Front plate: 13 in. wide with 1.5 in. of trim on both sides of the slot. The front plate uses a spring-loaded flap that snaps closed after each delivery. No screw holes on the exterior face, so the finished look stays clean. 

Rear plate: Hinged flap on the interior side for easy mail retrieval. Four screw holes at the corners for secure mounting. 

Mail opening: 10 in. W x 2 in. H, accepting standard letters, magazines, and large envelopes.
Total plate dimensions: 13 in. W x 4 in. H. Weight: 3 lbs (complete front-and-rear set).

For hollow-core doors, add the stainless steel mail slot sleeve (sold separately). The sleeve sits between the front and rear plates to prevent mail from dropping into the door cavity. 

Sleeve dimensions: 11.5 in. x 1.75 in. x 2.625 in.

Through-Wall Mail Slots

For installations where a door mount is not practical, the same front-and-rear plate design can be installed through a wall using the mail slot sleeve to bridge the gap between plates. The manufacturer recommends standard door installation for optimal performance; wall installations require custom fitting.
