Deltana DSB45B10B Square Hinge Ball Bearing Oil Rubbed Bronze

Product Description

The DELTANA DSB45B10B is a 4.5 x 4.5 inch square door hinge with ball bearings, finished in oil rubbed bronze. Built for architectural hardware applications, this hinge is sold as a pair and suits commercial and residential door installations where a traditional square-corner profile is required. The ball bearing construction reduces friction and wear over the life of the door, making it a reliable choice for high-cycle applications. The oil rubbed bronze finish provides a dark, hand-finished appearance consistent with period and transitional hardware styles.

This hinge is suited for interior and exterior door installations in residential and light commercial settings. It is commonly specified for entry doors, passage doors, and closet doors where a square-corner hinge is called for. The oil rubbed bronze finish coordinates with matching DELTANA lever sets, knobs, and other architectural hardware. Installers working on new construction or renovation projects will find this hinge appropriate for standard mortise hinge applications on wood doors and frames.

• 4.5 x 4.5 inch square hinge leaf profile for full-mortise door applications

• Oil rubbed bronze finish for a dark, hand-applied aesthetic

Compatibility

Designed as an OEM-style architectural replacement or new-installation hinge for standard full-mortise door applications requiring a 4.5 x 4.5 inch square hinge profile.

Installation Notes

Installation is performed by a carpenter, finish hardware installer, or general contractor. Power down any electric strike or access control hardware associated with the door before beginning work. Mortise the hinge leaf fully into the door edge and jamb to achieve a flush fit, using a sharp chisel and router jig as applicable. Follow local building codes for required hinge count per door weight and height.
