Rockford Process Free Swinging Overlay Five Knuckle Hinge, 270º Screw-on Dull Chrome, 50/Pairs, 849-26D

Rockford Process Overlay Hinge For 32 Mm Systems

Rockford Process overlay hinge in the 849-26D model is a semi-concealed, free swinging overlay five knuckle hinge that provides smooth door movement on institutional and cabinetry projects using the 32 mm hole system. The dull chrome finish on this hinge delivers a clean, professional look that aligns with other dull chrome hardware in a run. The hinge is designed as a free swinging 270 degree overlay hinge, so doors can open wide for better access to cabinet interiors where full access is important. Hospital grade tips on the hinge support use in demanding institutional environments where smoother edge detail is preferred at the hinge ends. A tight screw pin holds the knuckle assembly together securely, which supports long-term alignment of the leaves during repeated opening and closing.

Practical Details That Support Daily Door Use

• The five knuckle, free swinging design allows the hinge to rotate through 270 degrees, giving doors a wide opening arc so users gain better reach and visibility into cabinets without needing to remove items from the front.
• Hospital grade tips at the ends of the hinge barrel present a more finished edge, which suits institutional and hospital-oriented environments where hardware appearance and edge form are part of the overall hardware standard.
• Elongated holes on both leaves allow positional adjustment during installation, so the fitter can fine-tune door alignment relative to the frame without re-drilling when small layout variations exist.
• The frame leaf length of 1-3/4 inches provides a defined bearing surface on the frame, distributing load over that length and supporting stable door mounting once the hinge is fastened.
• The barrel height of 2-3/4 inches creates a tall knuckle stack, which helps spread the pivot support over a greater vertical distance for consistent swing on taller or heavier doors.
• Material thickness of 0.095 inches, or 2.4 mm, gives the hinge leaves a solid cross-section, which supports resistance to bending under normal door loads in institutional and cabinet installations.

Overlay Hinge Mounting And Adjustment Use

This semi-concealed overlay hinge works with the 32 mm hole system, so it aligns with cabinets drilled to that standard for predictable hinge positioning along the door and frame. The screw-on design allows the hinge to be mounted using screws through the leaves, creating a direct mechanical connection between the hinge and the door or frame surfaces. Elongated holes on both leaves give lateral and vertical adjustment during mounting, so doors can be shifted slightly before screws are fully tightened to achieve consistent reveals and smooth closing. The frame leaf length of 1-3/4 inches offers enough surface area for secure attachment, supporting repeatable screw placement along the leaf. The free swinging 270 degree movement lets the door travel through a large opening angle, which is useful where cabinets are positioned so that wide door opening is desired for workflow.

How This Semi-Concealed Hinge Performs In Use

Overlay Hinge Role In Institutional And Cabinet Settings

This free swinging overlay hinge from Rockford Process Control, Inc. is part of the institutional hinge category, so it suits environments where doors are operated frequently and hardware is part of the overall facility standard. The semi-concealed design leaves part of the hinge visible while the rest sits between door and frame, balancing appearance with access to mounting points. Hospital grade tips shape the ends of the barrel, which supports use on doors in healthcare and similar settings where hardware geometry is part of the design criteria. The available dull chrome finish provides a muted metallic appearance that coordinates with other dull chrome components, helping installers maintain a consistent look across cabinets, casework, and fixtures. As an overlay hinge, it positions the door over the cabinet frame edge, so the hinge supports a modern cabinet layout where the door face overlays the front of the case.

The hinge is designed for the 32 mm hole system, tying directly into cabinet lines drilled on that metric standard so layout is predictable along the run of doors. The barrel height of 2-3/4 inches gives the hinge a tall bearing stack, which distributes pivot forces across multiple knuckles during door movement. Material thickness of 0.095 inches, or 2.4 mm, gives each leaf a robust profile, supporting use on heavier doors that appear in institutional casework. A tight screw pin binds the five knuckle assembly, which keeps the leaves aligned under repeated use and supports consistent swing without excess play. With elongated holes on both leaves, the hinge offers flexibility during installation on both frame and door, allowing the installer to shift the hinge position slightly to correct for drilling tolerances while maintaining the intended overlay and reveal.

Details That Support Repeatable Hinge Installation

The screw-on mounting style of this overlay hinge uses screws through the leaves, which lets installers set hinges precisely along the 32 mm system line and pull the leaves flush to the mounting surfaces. Elongated holes in both leaves create adjustment zones that help bring multiple doors into alignment during casework installation, particularly where small drilling or framing variations exist. Frame leaf length of 1-3/4 inches gives a clear reference for screw spacing along the frame edge, aiding consistent locating from cabinet to cabinet. The five knuckle configuration provides multiple bearing points around the tight screw pin, which spreads friction and wear across the barrel and supports a stable swinging action.

The barrel height of 2-3/4 inches means the knuckle stack engages a larger section of the door edge, stabilizing the pivot for doors that see frequent operation in institutional settings. Material thickness of 0.095 inches, or 2.4 mm, supplies the leaves with enough depth to hold threads from the mounting screws securely and to resist deformation under normal door loads. The free swinging 270 degree rotation gives installers and end users a wide-opening door, which can simplify interior access and casework service. The dull chrome finish presents a professional appearance on exposed hinge areas, tying into other dull chrome components installed in the same project, and supporting a unified visual line in cabinets and fixtures.
