Deltana S44HDBB1B Square Hinge Heavy Duty Ball Bearing 4x4

Product Description

The DELTANA S44HDBB1B is a heavy-duty, ball-bearing square door hinge finished in flat black. It is designed for commercial and residential door applications where smooth, low-friction swing and long service life are required. The hinge measures 4 inches by 4 inches and ships as a pair, making it suitable for standard interior and exterior door installations. Ball bearings reduce wear on the pivot point and allow doors to swing consistently over high-cycle use. Licensed carpenters, door hardware installers, and general contractors typically specify this type of hinge for heavy door assemblies.

This hinge is used on residential entry doors, interior passage doors, and light commercial applications where a square-corner hinge profile is specified. The flat black finish suits modern, industrial, and transitional door styles. It is sold as a pair and is appropriate for projects requiring a consistent, matte dark finish across all door hardware. No specific compatible door brands or model numbers are stated in the product data.

Installation Notes

Installation is performed by carpenters, door hardware specialists, or general contractors using standard hand tools including a chisel and screwdriver or drill. Power down any electric door hardware and secure the door before removing existing hinges. Follow applicable local building codes for door hardware requirements. Do not over-drive fasteners into the hinge leaf, as this can distort the barrel and affect door swing alignment.
