The DELTANA MS211U3 is a mail slot with interior frame designed for installation in residential and commercial entry doors. The unit ships in a bright brass finish and includes the interior frame component, making it a complete through-door mail delivery assembly. Overall package dimensions are 15.3 inches in length, 4 inches in width, and 0.9 inches in height, with a package weight of 1.2 pounds. Licensed carpenters, door hardware installers, and general contractors typically specify this type of hardware for new construction and renovation projects where a clean, finished appearance on both sides of the door is required.
The MS211U3 is suited for interior and exterior door applications in residential entry doors and light commercial storefronts. The interior frame provides a finished appearance on the inside face of the door, which is standard for customer-facing or occupied spaces. The bright brass finish coordinates with matching architectural hardware in the same finish family. This slot is sold as a single unit and is appropriate for door thickness ranges common in residential framing and hollow metal door applications.
Designed as an OEM-style replacement or new-installation mail slot for residential and light commercial entry doors requiring a through-door mail delivery opening with an interior frame finish.
Installation is typically performed by a licensed carpenter or door hardware installer. The door must be properly templated and routed to the correct slot dimensions before mounting the exterior face plate and interior frame. Secure all fasteners per the manufacturer instructions before returning the door to service. Do not install on fire-rated door assemblies unless the product carries the appropriate fire rating listing.
