Rockford Process free swinging overlay hinge is a semi-concealed, five knuckle institutional hinge designed for projects using the 32 mm hole system. This design supports cabinet and casework layouts built around system drilling, so hinges align with existing patterns on production or retrofit jobs. The free swinging action allows doors to move through the full arc without spring resistance, which suits applications where controlled self-closing is not required.
This Rockford Process Control, Inc. hinge uses a dull chrome finish, giving a neutral, low-glare appearance that works well in functional environments. The hinge is classified as hospital grade with specific tips, so it is oriented to demanding institutional settings where hardware is subjected to regular use. As a semi-concealed hinge, part of the hardware remains visible while the functional geometry sits in line with the door and frame, helping maintain a clean but serviceable look.
The five knuckle configuration spreads movement across multiple joints, supporting smooth door travel from closed to full opening. A barrel height of 2-3/4 inches defines the hinge profile along the knuckle line, which helps installers visualize door edge coverage and clearance around adjacent components.
This free swinging overlay hinge uses a screw-on installation method, so both leaves fasten directly through the holes into the door and frame structure. Because the hinge is designed for the 32 mm hole system, the mounting pattern lines up with line-bored holes, streamlining layout on cabinets and institutional casework. The semi-concealed configuration positions part of the hinge within the overlay relationship between door and frame, managing how the door overlays the cabinet or frame face.
Elongated holes on both leaves introduce adjustment range during screw-on installation. This design lets the installer shift the hinge position slightly before tightening, which helps fine-tune door gaps and maintain consistent reveals across multiple doors in a run. The 1-3/4 inch frame leaf length and 2-3/4 inch barrel height give clear dimensional references when laying out screw lines, aligning hinges, and coordinating with adjacent hardware or trim pieces.
The .095 inch, or 2.4 mm, material thickness determines how the hinge seats on the surface, which influences the feel of the door when opening and closing. Because this hinge provides 270 degree opening, the door can rotate beyond a standard right-angle swing, giving broad access at the cabinet or opening where that range is desired.
This Rockford Process Control, Inc. hinge is categorized as an institutional hinge within the semi-concealed class, so it is oriented toward casework and door assemblies in facilities that expect frequent use. Being hospital grade with specific tips, it aligns with healthcare and related institutional environments where hinge ends are a visible detail. The dull chrome finish supports these settings by presenting a subdued, functional look on doors and frames.
Designed for the 32 mm hole system, this hinge integrates naturally into modular cabinet runs, medical casework, and storage units built on system drilling. Installers working on replacements or extensions in such layouts gain from a hinge whose hole pattern follows the same logic as the casework. The overlay configuration also supports door designs that sit over the face of the frame or cabinet, tying into many contemporary institutional cabinet constructions.
The 270 degree free swinging capability lets doors move well past 90 degrees, which is particularly useful where wide opening is needed for carts, equipment, or full-shelf access. The five knuckle design contributes to smooth motion as the door travels through this arc, helping the assembly operate comfortably over repeated cycles.
The tight screw pin in this hinge holds the knuckles together as a compact barrel, so the door movement tracks consistently each time it is opened and closed. This is significant in institutional corridors or rooms where many openings rely on predictable hinge action. The 2-3/4 inch barrel height further stabilizes the hinge axis along the door edge, contributing to a uniform swing and reducing variability between doors mounted with the same model.
Elongated holes on both leaves provide a practical adjustment window during installation. This feature allows small in-plane shifts to square doors relative to the frame and to keep reveal lines consistent from top to bottom. Installers can work within normal drilling tolerances and still achieve neat gaps along the edges of overlay doors.
The 1-3/4 inch frame leaf length defines how much bearing area sits on the frame, which helps distribute loads over a longer section of the jamb or cabinet stile. Combined with the .095 inch, or 2.4 mm, material thickness, the hinge presents a defined seating surface that influences how firmly the door feels supported at the pivot points.
The hinge is available in five finishes - gloss black, dull chrome, white, barrel brass, and stainless steel - so projects can match the hinge appearance to different room palettes or fixture sets. This flexibility helps standardize mechanical function while varying finish across departments or build phases.
The 375-26D model is a Rockford Process semi-concealed, free swinging overlay five knuckle hinge, so it serves institutional and cabinet applications needing overlay doors with visible but compact hinge hardware.
The hinge is designed for the 32 mm hole system, so its mounting layout aligns with standard line-boring patterns, supporting efficient positioning on modular cabinet and institutional casework runs.
This Rockford Process free swinging overlay hinge opens to 270 degrees, allowing doors to swing back for broad access where wide opening is beneficial at cabinets or institutional enclosures.
Elongated holes on both leaves allow minor adjustment during mounting, helping align doors, refine reveals, and accommodate small drilling variations while keeping hinge screws within the slots.
The .095 inch, or 2.4 mm, material thickness defines the leaf gauge, shaping how the hinge beds against door and frame surfaces and contributing to the installed feel of the swing.
This model is a dull chrome, hospital grade hinge available as part of a five-finish range, aligning color and performance expectations with institutional and cabinet projects.
The Rockford Process free swinging overlay hinge in dull chrome brings a semi-concealed, five knuckle, institutional-grade design together with 32 mm system compatibility. Its 270 degree opening, hospital grade tips, and tight screw pin support doors in demanding environments where smooth motion and clear access are priorities.
With a 1-3/4 inch frame leaf length, 2-3/4 inch barrel height, and .095 inch (2.4 mm) material thickness, this hinge gives clear dimensional references for layout and mounting. The elongated holes on both leaves add adjustment range, which aids in aligning overlays and reveals across a run of doors. For projects calling for a dull chrome institutional hinge with these specific characteristics, this 375-26D model from Wurth Baer Supply is positioned to match those requirements.
