Product Description

The DELTANA DSH35U1B is a 3.5 x 3.5 inch spring hinge finished in flat black. Spring hinges are self-closing door hardware components that use internal spring tension to return a door to its closed position automatically. This hinge installs on interior or exterior doors in residential and light commercial settings. It measures 3.5 inches in leaf width and 3.5 inches in leaf height, with a package length of 5 inches and a package width of 3.1 inches. At 0.7 pounds, it is a compact, single-unit component suited for standard door applications where code or building design requires a self-closing function.

The DSH35U1B is appropriate for use on passage doors, corridor doors, and other door assemblies that require automatic closure. The flat black finish suits modern, industrial, and matte-aesthetic installations. Carpenters, door hardware installers, and general contractors typically specify this hinge on projects where self-closing doors are required by fire code or building design standards.

Installation Notes

Spring hinges are installed by qualified carpenters or door hardware professionals. Power down any electric strike or access control hardware on the door before beginning work. A standard mortise chisel and screwdriver or drill with appropriate bit are typically required for proper seating of the hinge leaf into the door edge and frame. Confirm that door clearances and frame conditions meet applicable building code requirements before installation.
