Deltana S35R51B Radius Corner Door Hinge Flat Black

Product Description

The DELTANA S35R51B is a residential-grade door hinge with radius corners, designed for standard interior and exterior door installations. Measuring 3.5 x 3.5 inches with a 5/8-inch throw, it is built to residential thickness specifications and finished in a flat black coating. The hinge is sold as a pair and is suited for use on wood-framed doors in both new construction and replacement applications. Licensed contractors, finish carpenters, and experienced DIYers install this type of hinge during door pre-hanging or retrofit work. The flat black finish provides a clean, matte appearance consistent with modern and transitional door hardware aesthetics.

The S35R51B is intended for residential door applications where a radius corner profile is specified. It fits standard door prep locations and is appropriate for interior passage doors, closet doors, and light-duty exterior doors meeting residential thickness requirements. It is sold in pairs, making it straightforward to order the correct quantity for single-door applications. The flat black finish coordinates with matching architectural hardware in the same finish family from the same manufacturer.

Installation Notes

This hinge is typically installed by finish carpenters or general contractors during door hanging or hardware replacement. Power down any electric strike or access control hardware associated with the door frame before servicing. Use a sharp chisel and router or hinge jig to mortise the door and frame to the correct depth before fastening. Follow applicable building codes for door hardware installation in your jurisdiction.
