Deltana DSB4B3 Square Hinge Ball Bearing Bright Brass

Product Description

The DELTANA DSB4B3 is a 4-inch by 4-inch square door hinge with ball bearings, finished in bright brass. It is built for interior and exterior door applications where smooth, low-friction operation and a polished appearance are required. The ball bearing construction reduces wear on the hinge pin and knuckle assembly, making it well suited for doors that see frequent use. Licensed contractors, carpenters, and finish hardware installers specify this hinge for commercial and residential projects requiring a solid, properly rated door hinge in a classic square profile.

The DSB4B3 is appropriate for standard residential and light commercial door installations. Its 4-inch by 4-inch leaf dimensions make it compatible with most interior and exterior door preparations using a standard square-corner hinge mortise. The bright brass finish suits projects where a warm, polished metal look is specified by an architect or designer. It is sold as a pair, allowing a full two-hinge set for a single door to be ordered in one unit.

Installation Notes

Installation is typically performed by a licensed carpenter, door hardware installer, or general contractor. Power down any electric strike or access control hardware associated with the door before beginning work. Use a sharp chisel and router for accurate hinge mortise preparation to ensure proper leaf seating and door swing. Verify door weight and frequency-of-use rating against hinge specifications before finalizing the installation.
