Deltana S35R4BB5 Ball Bearing Hinge Antique Brass

Product Description

The DELTANA S35R4BB5 is a full-mortise ball bearing door hinge finished in antique brass and sold as a pair. It measures 3.5 inches by 3.5 inches with a 0.25-inch radius corner profile, making it suitable for standard interior and light-duty exterior door applications. The ball bearing mechanism reduces friction and wear over the life of the hinge, supporting smooth, consistent door operation. Constructed from solid brass, it delivers corrosion resistance and long-term finish stability. The antique brass finish provides a warm, traditional appearance suited to period-style or transitional architectural settings. Licensed contractors and finish carpenters are the primary installers.

This hinge is appropriate for residential and light commercial door installations where a radius corner mortise hinge is specified. The 3.5 x 3.5-inch leaf size fits standard interior passage doors and lighter exterior doors. The antique brass finish coordinates with period-appropriate door hardware sets. Units are sold in pairs, and case quantity is 50 pairs for wholesale or multi-unit project purchasing.

Installation is typically performed by a finish carpenter or licensed contractor using a chisel, router, and drill.

Power down any electric strike or access control hardware associated with the door before beginning work. Follow applicable local building codes for door hardware requirements in commercial settings.
