Deltana DSH45U32D Spring Hinge 4.5x4.5 Satin Stainless Steel

Product Description

The DELTANA DSH45U32D is a 4.5 x 4.5 inch spring hinge finished in satin stainless steel, designed for self-closing door applications in commercial and residential construction. The built-in spring mechanism returns the door to a closed position automatically after each use, making it a standard specification for fire-rated corridors, stairwells, and code-required self-closing assemblies. Weighing 1.2 pounds, the unit is built for durability in high-traffic openings. Installation is handled by finish carpenters, door hardware specialists, or licensed contractors working to applicable building codes.

This spring hinge is suited for interior and light-duty commercial door applications where self-closing hardware is required by fire codes or facility specifications. Typical installations include corridor doors, stairwell access doors, and tenant separation doors in multi-family or light commercial construction. The satin stainless steel finish provides corrosion resistance suitable for environments with moderate humidity exposure, such as restroom corridors or exterior-adjacent interior doors. Each unit is sold individually.

Installation Notes

Spring hinges are installed by finish carpenters or licensed door hardware contractors following door manufacturer specifications and applicable building codes. Ensure the door and frame mortise are correctly prepped for a 4.5 x 4.5 inch hinge before installation. Spring tension should be adjusted using the appropriate tension pin tool after mounting to achieve proper closure speed and latching force. Do not over-tension the spring mechanism, as this can cause premature wear or difficulty operating the door.
