Rockford Process Free Swinging Overlay Five Knuckle Hinge, 270º Screw-on Gloss Black - P860-1D

Rockford Process Hinge For Overlay Doors

Rockford Process free swinging overlay hinge gives you a semi-concealed, five knuckle solution for overlay doors where appearance and motion both matter. This hinge is classified as a semi-concealed hinge, so the hardware sits partly out of sight while still providing visible alignment points that installers can read quickly during layout. The hinge is designed as a free swinging overlay style, letting the door move without built-in closing force, which suits institutional and utility applications needing predictable, unassisted motion. Its five knuckle configuration distributes movement across more pivot points, which supports smoother travel through the swing arc on properly sized doors. As part of the Rockford Process Control institutional hinge family, this hinge fits jobs that call for consistent function and a familiar hardware format across multiple openings.

Key Overlay Hinge Details For Real Projects

• The barrel height of 2-1/2 inches (63.5 mm) gives the hinge a tall pivot section, which helps installers visually align multiple hinges on the door edge and frame so reveal lines stay consistent along the height of the opening.
• The material thickness of .083 inches (2.1 mm) provides a solid leaf cross-section, which supports a firm feel at the pivot and helps the hinge resist flexing during normal door operation in institutional or cabinet use.
• The 270 degree screw-on design allows the hinge to rotate through a wide swing arc when properly mounted, which can give doors generous opening range where the surrounding casework and clearances are laid out to suit that motion.
• The gloss black hinge finish delivers a dark, uniform appearance on the exposed portions of this semi-concealed hinge, which can visually tie in with other black hardware and trim on casework or fixtures in the same space.

Screw-On Overlay Hinge Installation Focus

This Rockford Process Control hinge uses a screw-on attachment style, so the leaves are fastened directly to the door and cabinet or frame with mechanical fasteners. That screw-on design lets installers position the semi-concealed overlay relationship by marking and drilling their own layout, which supports field adaptation across institutional or cabinet projects built to varying dimensions. The 270 degree swing rating defines the rotational capacity of the knuckle assembly, so door and casework layouts can be planned to take advantage of the wide movement where adjacent components allow. With a barrel height of 2-1/2 inches, hinge locations can be stepped off consistently from cabinet ends or rails using standard tape measurements for repeatable installation from opening to opening.

Using This Semi-Concealed Hinge On The Job

Where This 2-1/2 Inch Barrel Hinge Works

This hinge falls under the institutional hinges category, positioning it for applications such as facility casework, storage units, and similar installations where repeated use and straightforward motion are important. As a semi-concealed hinge, part of the hardware remains visible, giving installers and maintenance staff a clear view of the five knuckle alignment along the door edge. The overlay design means the door face overlays the case front, which suits cabinets and enclosures built with a frontal plane that the door covers rather than fitting flush inside an opening. The gloss black finish helps the exposed sections of the hinge blend with darker casework finishes or with other black fittings in the room, keeping the hinge visually consistent where it shows at the door edge.

Why These Rockford Details Support Repeatable Results

The five knuckle layout on this Rockford Process free swinging overlay hinge breaks the pivot into multiple smaller segments, which can help the door travel smoothly through its available swing when the door and frame are square. Because the hinge is rated for 270 degree motion, designers and installers can account for the extended door travel during layout, avoiding interference where walls, adjacent cabinets, or furniture sit near the opening. The .083 inch (2.1 mm) material thickness adds substance at the leaves, supporting a firm bearing at the knuckles that feels solid during daily use on institutional casework. With a 2-1/2 inch (63.5 mm) barrel height, installers can repeat vertical positioning measurements from one opening to the next, promoting alignment of hinge barrels across banks of doors. The gloss black appearance also provides a clear visual contrast against light-colored doors, which can aid quick identification of hinge positions during installation and any later adjustment of door fit within the overlay layout.
