The DELTANA MS212U19 is a through-door mail slot with an interior flap, designed for residential and light commercial entry doors. The exterior plate measures 13.4 inches in length and installs flush against the door face, allowing mail and small parcels to pass through while the interior flap provides a barrier against drafts and debris. Finished in black, this slot suits both traditional and contemporary door applications. Installation is handled by locksmiths, carpenters, or general contractors working on door hardware.
This mail slot is suited for wood, composite, or hollow-core doors in residential entryways and light commercial lobbies. The interior flap adds a functional layer that keeps out wind and insects between deliveries. The black finish coordinates with standard black door hardware sets. At 1.7 pounds, the unit is straightforward to handle and position during installation.
Designed as an OEM-style replacement or new-installation mail slot for standard residential and light commercial entry doors with adequate door thickness to accommodate a through-door slot assembly.
Installation is typically performed by a carpenter or locksmith using standard hole-saw and chisel tools to cut the door opening to the required slot dimensions. Verify door thickness is sufficient to accept the full depth of the assembly before cutting. Follow all applicable local building codes for door hardware installation. Ensure the door is secured and stable before beginning any cutting or fastening work.
