Deltana S44R4HDB1B 4x4 Radius Heavy Duty Ball Bearing Hinge

Product Description

The DELTANA S44R4HDB1B is a heavy-duty ball bearing door hinge measuring 4 inches x 4 inches with a 0.25 inch radius corner profile. Built for demanding applications, it features a ball bearing mechanism that reduces friction and supports smooth, consistent door operation over extended use. The paint black finish provides a clean, uniform appearance suited to both interior and exterior door installations. This hinge is sold as a pair and is typically installed by carpenters, contractors, or door hardware technicians working on commercial or residential projects requiring a durable, high-cycle hinge solution.

The S44R4HDB1B is appropriate for use on heavy interior or exterior doors where a standard hinge would be undersized. The heavy-duty construction and ball bearing design make it well-suited for high-traffic doorways in commercial buildings, multi-family residential properties, and institutional settings. The radius corner geometry fits standard door frame mortises cut for 4 x 4 inch hinges. Each unit ships as a pair, allowing a two-hinge installation on a single door with one order quantity.

Key Features

• 4 inch x 4 inch leaf size with 0.25 inch radius corners for standard mortise compatibility
• Ball bearing construction reduces operational friction and extends service life on heavy or high-cycle doors
• Heavy-duty rating supports solid core and heavier door assemblies
• Paint black finish provides a consistent, low-sheen appearance that accepts touch-up paint if needed
• Sold as a pair — one order quantity equals two hinges

Compatibility

Designed as an OEM-style replacement or new-installation hinge for doors mortised to accept a 4 inch x 4 inch radius corner hinge plate.

Installation Notes

Installation is typically performed by a licensed carpenter or door hardware technician using a chisel, mallet, and drill with appropriate bit sizes for the fastener pattern. Remove the door from the frame and secure it safely before beginning hinge work. Ensure the mortise depth matches the hinge leaf thickness to achieve a flush mount and proper door clearance. Follow local building codes for door hardware requirements in commercial or fire-rated assemblies.
