Deltana DSH35U4 Spring Hinge 3.5x3.5 in Satin Brass

Product Description

The DELTANA DSH35U4 is a 3.5 x 3.5 inch spring hinge designed for self-closing door applications in residential and light commercial construction. The spring mechanism applies consistent closing force each time the door is opened, eliminating the need for a separate door closer on standard-weight interior doors. Finished in satin brass, this hinge offers a traditional look that coordinates with a wide range of architectural hardware. At 0.7 pounds, the unit is lightweight yet built from solid brass stock consistent with DELTANA's architectural hardware line. Licensed carpenters, finish carpenters, and door hardware installers are the primary tradespeople handling this product.

The DSH35U4 is suited for interior residential doors and light-duty commercial doors where self-closing function is required by code or desired by the end user. Typical applications include corridor doors, utility room doors, and any opening where a door must return to the closed position without manual effort. The satin brass finish suits traditional and transitional interior door designs. Sold individually, making it easy to order the exact quantity needed for a specific job.

Installation Notes

Spring hinges are typically installed by licensed carpenters or door hardware specialists. Most door frames require a minimum of two spring hinges to provide adequate self-closing force; local building codes or fire-door requirements may specify the number of hinges per door leaf. Adjust spring tension using the supplied tension pin before final installation to achieve the desired closing speed. Ensure the door and frame are properly aligned and plumb before setting hinge screws to avoid binding.
