Rockford Process free swinging hinge is a semi-concealed institutional hinge designed for overlay doors where consistent swing and long service life matter. This five knuckle hinge supports a smooth, free swinging action, which keeps doors moving without spring resistance and helps doors stay where they are moved in routine use. The hinge is built in stainless steel, giving corrosion-resistant performance that suits demanding environments such as institutional millwork and casework exposed to frequent cleaning. As a semi-concealed hinge in the institutional hinges category, it leaves the knuckle visible for inspection while keeping much of the hardware out of sight, which balances appearance with practical access. The hinge is designed around the 32 mm hole system, so it lines up with standard system-bored cabinetry to streamline layout and drilling on casework runs. This hinge configuration supports overlay applications where consistent clearances and repeatable alignment are important from cabinet to cabinet.
This stainless steel overlay hinge is a 270 degree screw-on design, so it fastens directly to the frame and door using conventional screw installation rather than press-in components. That screw-on approach suits on-site work where drilling and driving are the primary tools and supports retrofit situations where existing pilot locations can be reused or adjusted. Because the hinge is designed for the 32 mm hole system, it works naturally with system line boring patterns on cabinets and casework, keeping hinge centers aligned along the vertical line. The material thickness of 0.095 inch, or 2.4 mm, gives the leaves a solid feel as they seat against the door and frame, which helps resist flexing during fastening and contributes to alignment that stays true after installation.
This semi-concealed hinge is categorized as an institutional hinge, so it is suited to cabinets and casework built for higher traffic environments such as hospitals and similar facilities that favor robust hardware. The stainless steel construction of the 376-SS model supports use where moisture and cleaning agents are common, because stainless material stands up well to repeated exposure in those settings. Its hospital grade tips give the exposed hinge ends a smooth profile that aligns with institutional expectations for safety along the hinge edge. The 270 degree opening capability allows the door to swing well past 180 degrees relative to the cabinet, which helps doors clear the opening fully on units where wide access is needed for equipment, storage, or maintenance tasks. As a free swinging hinge, it avoids built-in spring force, making it suitable where doors are opened and left in various positions during normal routines.
The hinge being designed for the 32 mm hole system ties directly into modern cabinet manufacturing, because it lets the installer or fabricator use standard line boring equipment to locate hinge positions along a consistent grid. That alignment shortens layout time and supports fast duplication of drilling patterns across multiple cabinets, which is valuable on institutional projects with many identical units. As an overlay hinge, it supports door designs that cover the cabinet front frame or case edge according to the intended overlay dimension, which helps create a clean frontal appearance while still using a semi-concealed institutional hinge. The free swinging five knuckle barrel, standing 2-3/4 inch tall with a material thickness of 0.095 inch, offers a substantial pivot that carries door weight across multiple knuckles, which promotes smooth motion under repetitive use. Elongated holes in both leaves give a useful adjustment range during installation, letting the installer nudge the hinge position to align overlays and reveals after the screws are driven. The tight screw pin running through the knuckles keeps the leaves stable over time, which helps protect that fine-tuned adjustment and reduces the potential for sagging or shifting during long-term service in active facilities.
The Rockford Process 376-SS is a semi-concealed institutional five knuckle hinge for overlay applications, which suits heavier-use cabinetry where visible knuckles and robust construction are preferred.
The stainless steel overlay hinge opens to 270 degrees, allowing doors to swing back against adjacent surfaces and providing wide access to the cabinet interior in institutional settings.
The hinge is designed for the 32 mm hole system, so it aligns with standard line-bored patterns and simplifies drilling, layout, and repeatable hinge placement on production or jobsite work.
The frame leaf length is 1-3/4 inch, providing a known bearing surface on the frame that helps with repeatable layout and stable screw placement during installation.
Elongated holes on both leaves allow slight movement of the hinge position while tightening screws, which helps fine-tune overlays and door reveals for a cleaner finished appearance.
The hinge is available in Gloss Black, Dull Chrome, White, Barrel Brass, and Stainless Steel, so finish can be matched to surrounding hardware or design standards.
The Rockford Process 376-SS stainless steel overlay hinge brings a five knuckle, free swinging design together with institutional details such as hospital grade tips, a tight screw pin, and elongated holes on both leaves. The 270 degree screw-on construction, 32 mm hole system design, and 1-3/4 inch frame leaf length support straightforward layout whether work is shop-built or installed on site. For projects calling for a semi-concealed institutional hinge in stainless steel with these specific dimensions and operating characteristics, this model offers a targeted option ready to be specified into casework runs or used as a consistent choice across a facility.
