Tuff Stuff 103 Polished Brass US3 10" X 3" Letter Slot

Tuff Stuff 103 Polished Brass Letter Slot

The Tuff Stuff 103 is a polished brass letter slot designed for installation in a door or wall. It features a single spring-loaded flap on the outside and includes a matching inside trim plate with screws for a finished look. The unit meets postal regulation opening sizes for standard mail delivery. This hardware suits homeowners replacing an existing slot or adding a secure mail entry point.

Installation checks before ordering

Verify that your door or wall thickness can accommodate the supplied trim plate and screw length. Confirm the rough opening matches the inside dimensions of 1-5/8" by 7-3/4" so the internal trim fits flush. Ensure the exterior face has enough flat surface for the 3" by 10" outer flange to sit securely. The spring-loaded flap requires clearance to swing freely without obstruction from interior hardware or weather stripping.

Behaviour under sustained daily use

The spring-loaded flap returns to a closed position after each insertion, keeping drafts and moisture out during repeated deliveries. Polished brass construction resists corrosion from outdoor exposure better than unfinished metals. The fixed flap tension is designed for standard letter volumes rather than heavy parcel traffic. Regular lubrication of the hinge point will maintain smooth operation over years of continuous service.
