Deltana DSB55B10B Square Ball Bearing Hinge Oil Rubbed Bronze

Product Description

The DELTANA DSB55B10B is a 5-inch x 5-inch square ball bearing hinge finished in oil rubbed bronze. Ball bearing construction reduces friction and wear on heavily used doors, making this hinge suitable for high-cycle residential and light commercial applications. The oil rubbed bronze finish provides a dark, hand-applied appearance consistent with traditional and transitional architectural hardware styles. Sold as a pair, this hinge is sized for full-inset door installations where a larger, heavier hinge leaf is required for proper load distribution. Licensed contractors and finish carpenters are the typical installers.

This hinge is designed for interior and exterior door installations where a square-corner, heavy-duty hinge is specified. Common applications include entry doors, passage doors, and commercial-grade interior doors that require smooth, low-maintenance operation over extended service life. The 5-inch x 5-inch leaf size suits heavy or oversized door slabs where standard 4-inch hinges would be undersized for the load. The oil rubbed bronze finish coordinates with matching architectural hardware in the same product family.

Installation Notes

Installation is performed by licensed carpenters, finish contractors, or door hardware specialists. Power down any associated door access control or electric strike circuits before working on a door frame. Mortise the hinge leaf flush with the door edge and frame jamb to ensure proper door alignment and gap consistency. Follow local building codes for door hardware specifications on rated assemblies or egress doors.
