The DELTANA S35R5HD1B is a heavy duty radius corner door hinge finished in flat black. It measures 3.5 x 3.5 inches with a 0.625-inch throw, built for demanding door installations where standard-duty hinges are insufficient. The hinge is sold as a pair and is suited for commercial or high-traffic residential door applications. Licensed contractors, door and hardware installers, and finish carpenters are the typical trades working with this component. The flat black finish provides a clean, matte appearance consistent with modern architectural hardware specifications.
This hinge is appropriate for interior and exterior door applications requiring a heavy duty rating. The radius corner profile fits standard mortise preparations used on pre-hung doors and frames. It is commonly installed on passage doors, entry doors, and utility doors where elevated cycle life and load capacity are required. The flat black finish coordinates with contemporary door hardware sets in both residential and light commercial settings.
Designed as an OEM-style replacement or new-installation hinge for standard mortised residential and light commercial door frames requiring a 3.5 x 3.5-inch radius corner hinge.
Installation is performed by finish carpenters, door hardware installers, or licensed contractors following applicable building codes. Mortise the hinge leaf into the door edge and jamb to achieve a flush fit before fastening. Ensure the door is properly supported and the frame is plumb and square prior to final fastening. Follow local building and fire codes when installing hinges on rated door assemblies.
