Deltana S44R5HDB1B Heavy Duty Ball Bearing Door Hinge Flat Black

Product Description

The DELTANA S44R5HDB1B is a heavy-duty ball bearing door hinge with a radius corner profile, sold as a pair. It measures 4 inches x 4 inches with a 5/8-inch radius corner and a leaf thickness of 0.75 inches. Built for demanding door applications, the hinge uses ball bearings to reduce friction and support consistent, smooth swing cycles under load. The flat black finish is applied over solid construction materials suited for architectural hardware use. Licensed contractors and finish carpenters install this hinge on commercial and residential doors where a heavier-duty option is required over standard residential hinges.

This hinge is appropriate for interior and exterior door installations where a 4 x 4 inch heavy-duty hinge is specified. The radius corner profile fits standard mortise cuts on most pre-hung door frames. It is commonly used on wood doors in commercial light-duty and residential applications where ball bearing performance and a flat black architectural finish are specified by design or code. Each order covers one pair of hinges.

Compatibility

Designed as an OEM-style replacement or new-installation hinge for doors requiring a 4 inch x 4 inch heavy-duty ball bearing hinge with a radius corner profile and flat black finish.

Installation Notes

Installation is performed by a licensed carpenter, finish contractor, or door hardware installer. Power down any access-control or electric strike hardware associated with the door before disassembling the frame. Use a sharp mortise chisel and router template to ensure a clean, flush hinge pocket before setting the leaf. Follow applicable building and fire codes when replacing or installing hinges on rated door assemblies.
