Deltana S44R4HDB10B 4x4 Heavy Duty Ball Bearing Hinge

Product Description

The DELTANA S44R4HDB10B is a heavy-duty ball bearing door hinge measuring 4 inches x 4 inches with a 1/4-inch radius corner profile, finished in oil rubbed bronze. Designed for high-traffic commercial and residential door applications, it uses precision ball bearings to reduce pivot friction and extend service life under repeated use. The oil rubbed bronze finish is applied over solid material construction, providing corrosion resistance and a consistent architectural appearance. This hinge is installed by carpenters, general contractors, and finish hardware specialists as part of door frame and slab assemblies requiring a durable, low-maintenance pivot point.

This hinge suits interior and exterior door installations where a 4-inch heavy-duty hinge is specified. Typical applications include commercial entry doors, heavy solid-core residential doors, and institutional settings where standard-weight hinges are inadequate. The radius corner profile is compatible with pre-mortised door frames cut to a 1/4-inch radius specification. It is sold as a pair, making it straightforward to order the correct quantity for a standard two- or three-hinge door application.

Key Features

• 4 x 4 inch leaf size with 1/4-inch radius corners for standard mortise compatibility
• Ball bearing pivot construction reduces friction and wear under heavy door loads
• Heavy-duty rating suitable for solid-core and commercial-grade door assemblies
• Oil rubbed bronze finish provides a consistent, low-sheen architectural appearance
• Sold as a pair to simplify per-door ordering

Compatibility

Designed as an OEM-style architectural replacement or new-installation hinge for doors mortised to accept a 4 x 4 inch hinge with a 1/4-inch radius corner profile.

Installation Notes

Installation is performed by a licensed carpenter or finish hardware installer using a chisel or router jig to cut a precise mortise into the door edge and frame. Confirm door weight and frequency of use match the heavy-duty rating before installation. Follow the door manufacturer's hinge spacing specifications and any applicable local building code requirements for door hardware. Avoid over-driving fasteners, as this can strip the mortise and misalign the hinge leaf.
