Deltana S35R4BB15 Ball Bearing Door Hinge Satin Nickel

Product Description

The DELTANA S35R4BB15 is a 3-1/2 inch x 3-1/2 inch ball bearing door hinge with a radius corner profile and a satin nickel finish. Ball bearing construction reduces friction during operation, making this hinge well suited for doors that see frequent use. The 1/4 inch radius corner geometry provides a clean, standard fit at the mortise. This hinge is sold as a pair and is installed by carpenters, finish contractors, and door hardware specialists in both residential and light commercial applications.

This hinge is appropriate for interior and exterior door installations where a standard 3-1/2 inch mortise hinge is specified. The satin nickel finish blends with a wide range of door hardware finishes and is commonly specified on residential entry, passage, and closet doors. The ball bearing mechanism supports smooth, consistent operation on solid wood and hollow core doors alike. Each sales unit contains one pair of hinges.

Installation Notes

Installation is performed by a finish carpenter or door hardware installer using a chisel and router to prepare the mortise to the correct leaf dimensions. Power down any electric strike or access control hardware associated with the door frame before beginning work. Follow local building codes for the number of hinges required per door leaf based on door height and weight. Do not overtighten hinge screws into soft wood frames without backing or appropriate anchor hardware.
