Deltana S35R4BB4 Ball Bearing Door Hinge Satin Brass

Product Description

The DELTANA S35R4BB4 is a solid brass ball bearing door hinge designed for residential and light commercial door installations. Measuring 3.5 inches x 3.5 inches with a 0.25 inch radius corner, this hinge features an integrated ball bearing mechanism that reduces friction and supports smooth, consistent door operation over extended use cycles. The satin brass finish provides a clean, traditional appearance suited to interior and exterior door applications. Licensed contractors, carpenters, and door hardware installers work with this hinge in new construction and renovation projects where a durable, quality-finished bearing hinge is specified.

This hinge is appropriate for standard residential door frames and light commercial door applications requiring a 3.5 inch x 3.5 inch hinge with a radius corner profile. The ball bearing construction makes it well suited for higher-frequency doors such as entry doors, office doors, and passage doors where smooth pivot action and long service life are priorities. It is sold as a pair and is stocked in case quantities of 50 units for trade and contractor purchasing.

Installation Notes

Installation is performed by carpenters, door hardware specialists, or general contractors.

Mortise the hinge leaf flush with the door edge and jamb to ensure proper door alignment and prevent binding. Follow applicable local building codes for door hardware installation in commercial applications.
