Deltana S44R4HD1B Heavy Duty Door Hinge Flat Black

Product Description

The DELTANA S44R4HD1B is a heavy-duty door hinge finished in flat black, designed for commercial and residential door installations where durability and consistent operation are required. Measuring 4 inches by 4 inches with a 1/4-inch radius corner profile, this hinge suits standard full-mortise door applications. The flat black finish provides a clean, uniform appearance compatible with modern and transitional architectural styles. Sold as a pair, it is typically installed by carpenters, finish contractors, and door hardware specialists working on interior or exterior door frames requiring a heavier-gauge hinge.

This hinge is suited for residential and light-commercial door installations where a heavy-duty hinge is specified. The 4 inches x 4 inches leaf size covers standard door thicknesses and widths commonly found in entry, passage, and utility door applications. The 1/4-inch radius corner allows drop-in replacement or new installation in mortise preparations routed to that corner specification. Installers working on high-traffic doors or solid-core door slabs will benefit from the heavy-duty construction rating.

Installation Notes

Installation is typically performed by a finish carpenter or door hardware installer. Power down any associated electric strike or access control hardware before working on the door frame. Mortise preparation should match the 4 inches x 4 inches leaf dimensions and 1/4-inch radius corner profile before seating the hinge. Follow applicable building codes for door hardware requirements on fire-rated or egress door assemblies.
