Deltana DSB4NB19 Square Hinge Ball Bearings 4x4 Black

Product Description

The DELTANA DSB4NB19 is a 4 inches x 4 inches square door hinge with ball bearings, finished in black. Manufactured from solid materials by Deltana, a specialist in architectural and door hardware, this hinge is built for consistent operation under regular use. The ball bearing construction reduces friction and wear on the pivot point, making it well suited for doors that see frequent cycling. Sold as a pair, it installs on standard residential and light commercial door applications where a clean square corner profile and durable finish are required by the spec or the job.

This hinge is appropriate for interior and exterior door installations where a square-corner hinge profile is specified. The black finish suits applications where dark hardware finishes are called for by the project spec, designer, or property owner. Typical installations include entry doors, passage doors, and commercial storefront doors. A licensed carpenter, door hardware installer, or general contractor typically handles final installation, though the straightforward bolt pattern makes it accessible for qualified trade professionals across disciplines.

Installation Notes

Power tools and a sharp chisel are typically used to mortise hinge leaves flush into the door edge and frame jamb. Confirm door weight and frequency of use to verify the hinge size is appropriate before installation. Always ensure the door is properly supported and the frame is plumb and square before fastening. Follow applicable local building codes and manufacturer fastener recommendations for door hardware installations.
