Deltana DSB4B4 Square Hinge Ball Bearing Satin Brass

Product Description

The DELTANA DSB4B4 is a 4-inch by 4-inch square door hinge with ball bearings, finished in satin brass. It is built for architectural and door hardware applications where smooth, quiet operation and long service life are required. The ball-bearing construction reduces pivot friction, making this hinge well-suited for heavy or frequently cycled doors. Licensed carpenters, door installers, and finish hardware contractors typically specify and install this type of hinge on both residential and light commercial projects. The satin brass finish is applied over solid brass construction, providing corrosion resistance and a refined appearance consistent with architectural-grade hardware standards.

The DSB4B4 is designed for use on interior and exterior swinging doors in residential and light commercial construction. It fits standard door and frame preparations that accept a 4-inch by 4-inch square corner hinge. Typical applications include entry doors, passage doors, and interior doors where a full-mortise, square-corner hinge is specified. The hinge is sold as a pair, making it easy to order by door leaf count. It suits projects where architectural hardware specifications call for a satin brass finish to coordinate with door hardware sets.

Installation Notes

Installation is typically performed by a licensed carpenter or door hardware installer. Mortise the hinge leaf into the door edge and frame jamb using a sharp chisel or router jig, ensuring the leaf sits flush with the wood surface. Verify door weight and frequency of use to confirm the correct number of hinges per door leaf before installation. Follow applicable local building codes for door hardware requirements on rated assemblies.
