Deltana MS212 13-1/8" x 3-5/8" Solid Brass Mail Slot with Interior Flap

The MS212 plate measures 13-1/8 x 3-5/8 inches overall, and the slot door opening is 11 x 2-3/8 inches. Cut the through-hole to the 11 x 2-3/8 inch slot dimension, not the plate size, so the frame has material to bear on all four sides.

The interior flap is part of the MS212, so you get the exterior plate and the hinged interior flap in one order. There is no separate interior trim to buy. If you want just a lined sleeve for the hole rather than a flapped slot, that is a different part, like the Emtek 2281 Mail Slot Sleeve.

Only if your current opening is 11 x 2-3/8 inches or smaller and the existing plate footprint is under 13-1/8 x 3-5/8 inches. A larger old cutout will show around the new plate, and the MS212 is a fixed size, so measure the hole before ordering rather than the old plate.

No. The Deltana MS212 is a solid brass mail slot measuring 13-1/8 inches by 3-5/8 inches with an interior flap and a slot door opening of 11 inches by 2-3/8 inches, and it ships in a poly bag with mounting screws. The Emtek 2281 is a mail slot sleeve, which is the tube that lines the through-hole in the door rather than the exterior plate and flap assembly. On a through-door installation the two do different jobs: the MS212 covers and closes the opening, while a sleeve finishes the inside of the cut. If the buyer is replacing a worn exterior plate and hinged flap, the MS212 is the part; a sleeve will not close the opening.

The flap opening is 11 x 2-3/8 inches, so a No. 10 business envelope and a standard letter pass through flat. Anything thicker than the 2-3/8 inch dimension, like a bound catalog or a small parcel, will not.

Solid brass throughout, both the exterior plate and the flap, with brass listed as the substrate rather than a coating over pot metal or steel. That matters on an exterior door where a plated part will pit and peel at the edges after a few seasons.

Mounting screws ship in the poly bag with the slot. You will still need a drill and jigsaw to cut the 11 x 2-3/8 inch opening, and screws long enough for your door thickness if the door is unusually thick.

Nine finishes: PVD Polished Brass, Polished Brass, Antique Brass, Oil Rubbed Bronze, Brushed Nickel, Antique Nickel, Polished Chrome, Brushed Chrome, and Paint Black. If you are standardizing a building and the doors already carry lacquered polished brass, the PVD version holds its color far longer outdoors than standard lacquered brass, which is the usual reason a property manager ends up replacing slots twice.

The Deltana MS212 supplies the 13-1/8 inch by 3-5/8 inch solid brass mail slot with an interior flap and the mounting screws, covering the face of the door around an 11 inch by 2-3/8 inch slot door. It does not line the cut through the door itself. The Emtek 2281 mail slot sleeve is the sleeve-type part for that inside surface. Confirm the sleeve opening matches the cut you are making for the MS212 before ordering the pair together, since the two are separate manufacturers and are not dimensionally matched to each other.

Deltana classifies the MS212 as commercial, and it is an exterior door part. Solid brass construction is what carries it in a multi-family entry or an office door where a zinc or aluminum slot gets loose at the flap pivot.
