Deltana DSH4R5USPW Spring Hinge 4x4 5/8in Radius Prime Coat

Product Description

The DELTANA DSH4R5USPW is a 4-inch x 4-inch spring hinge with a 5/8-inch radius corner and a prime coat finish, designed for self-closing door applications in residential and light commercial construction. The spring mechanism applies consistent closing tension without a separate door closer, making it suitable for interior and exterior doors where code or occupancy requirements demand self-closure. At 0.8 pounds, the unit is sized for standard door weights and thicknesses. The prime coat finish accepts field painting, giving installers flexibility to match the door or frame finish on site.

This spring hinge is used in residential construction, commercial tenant improvement, and institutional settings where doors must self-close. Typical applications include corridor doors, utility room entries, and doors separating attached garages from living spaces where self-closing hardware is required by building code. It is installed by carpenters, finish hardware installers, and general contractors as part of a door prep and hang sequence. The hinge is sold individually and is available in case quantities of 50 for larger projects.

Key Features

• Self-closing spring mechanism eliminates the need for a separate surface-mounted door closer on lighter doors
• 4 inches x 4 inches leaf size suits standard residential and light commercial door applications
• 5/8-inch radius corners for clean, consistent fit in pre-routed door and frame mortises
• Prime coat finish accepts field-applied paint for a matched or custom appearance
• Compact profile at 5.2 inches length x 2.7 inches width x 0.8 inches height
• Lightweight at 0.8 pounds, reducing cumulative door weight on multiple-hinge installs

Compatibility

Designed as an OEM-style replacement or new-installation spring hinge for standard mortise hinge applications on residential and light commercial doors with a 4-inch x 4-inch hinge prep and 5/8-inch radius corners.

Installation Notes

Spring hinges are typically installed by carpenters or finish hardware contractors as part of a door hang. Mortise the door edge and frame jamb to the correct leaf dimensions before installation, and verify that the door stop and frame clearances meet local building code requirements for self-closing assemblies. Adjust spring tension using the tension adjustment pin included with the hinge before fully seating the hinge pin. Never force the tension pin with tools that could damage the spring cartridge.
