Deltana DSH45U3 Spring Hinge 4.5x4.5 Inches Bright Brass

Product Description

The DELTANA DSH45U3 is a 4.5 x 4.5 inch spring hinge finished in bright brass, designed for self-closing door installations in commercial and residential applications. Spring hinges store mechanical tension to return a door to the closed position automatically, making them a standard choice wherever building codes or facility requirements mandate self-closing doors. Constructed from solid brass, the DSH45U3 delivers corrosion resistance and dimensional stability suited to high-cycle door hardware environments. The bright brass finish provides a polished, traditional appearance consistent with period and transitional architectural hardware specifications.

This spring hinge is appropriate for interior and light-duty commercial door applications where a self-closing function is required. Typical installation scenarios include corridor doors, stairwell access doors, and tenant-space entry doors in residential multifamily and light commercial construction. Licensed carpenters, finish contractors, and door hardware installers are the primary trades specifying and installing this hinge. It is sold individually, making it suitable for single-door projects or replacement installations where only one leaf position requires service.

Installation Notes

Installation is typically performed by a finish carpenter or licensed door hardware installer. Tension adjustment on spring hinges requires a spring tension tool or the supplied adjustment pin; doors should be propped open and the spring fully released before adjusting tension to avoid injury. Verify that the door and frame mortise dimensions match the 4.5 x 4.5 inch leaf size before installation. Consult applicable building and fire codes, including IBC and NFPA 80, when installing self-closing hardware on rated assemblies.
