Deltana OK5032B3UNL-L Olive Knuckle Hinge Unlacquered Brass

Product Description

The DELTANA OK5032B3UNL-L is a solid brass olive knuckle hinge measuring 5 inches in leaf height by 3.25 inches in width, finished in unlacquered bright brass. Olive knuckle hinges are a traditional architectural hardware style recognized by their distinctive elongated, barrel-shaped knuckle joint. This hinge ships as a single unit and is intended for installation on interior or exterior doors where period-appropriate or decorative hardware is specified. The unlacquered finish allows the brass to develop a natural patina over time, which is a common requirement on restoration and historically sensitive projects.

This hinge is suited for residential and light commercial door applications where architectural detail is a priority. Typical installations include entry doors, interior passage doors, and cabinetry on projects specifying traditional or transitional hardware profiles. Finish carpenters, millwork installers, and general contractors handling architectural hardware scopes are the primary trades working with this product. The unlacquered bright brass finish is specified when a living finish that ages naturally is preferred over a protected or lacquered surface.

Installation Notes

Installation is performed by finish carpenters or qualified door hardware installers. Power down any electric strike or access control hardware integrated into the door frame before beginning hinge work. Mortise the hinge leaf flush to the door edge and jamb to ensure proper door swing and gap clearance. Do not overtighten fasteners into solid brass, as the material is softer than steel and threads can strip if excessive torque is applied.
