Rockford Process overlay hinge is a free swinging five knuckle hinge designed to deliver a 270 degree door swing, which lets doors open very wide for clear access to cabinet interiors and hardware during daily use or service work. The hinge is a semi-concealed institutional hinge, so part of the hinge is visible while the working geometry stays discreet, which suits installations where function and straightforward appearance matter. This model is specified as hospital grade tips, which provides a smooth, finished end detail on the knuckles that helps present a professional look on medical or institutional casework. The hinge material is stainless steel, which provides a robust hinge body that stands up to demanding commercial or institutional environments where metal components see frequent operation. The design is set up as a screw-on style hinge, so the leaves fasten directly to the door and frame, allowing installers to position and secure the hardware using standard screw-driving tools during casework builds or retrofits.
This stainless steel overlay hinge is designed as a screw-on hinge for overlay applications, so the door overlays the cabinet frame while the leaves fasten with screws through the elongated holes to both the door and frame. Because it is designed for the 32 mm hole system, the hinge works with rows of holes drilled on that pattern, allowing installers to place hinge positions along standard line-boring layouts on cabinet sides or frames without custom spacing. The elongated holes on both leaves provide some working range around those 32 mm reference points, which helps align overlay reveals and keep door gaps even across multiple doors on a run. With a framed leaf length of 1-3/4 inches and a barrel height of 2-3/4 inches, the hinge offers well-defined geometry that installers can reference when laying out hinge locations on institutional casework, closets, or service cabinets where wide-opening overlay doors are required.
This Rockford Process Control P376-SS hinge sits in the institutional hinge class as a semi-concealed overlay hinge, which makes it suitable for cabinets built on the 32 mm hole system in healthcare, lab, or commercial environments. The free swinging design with a 270 degree door swing allows doors to open well past 180 degrees, which helps staff move carts or equipment in and out of cabinets without the door obstructing the opening. Because it is an overlay hinge, the door edge projects over the cabinet frame, and the hinge geometry supports that overlay while still allowing the door to fold back for that wide opening angle. The hospital grade tips on the five knuckle hinge give the projection of the knuckles a finished tip shape, which matches the expectations in hospital-grade casework where hinge ends are part of the visible hardware line along corridor or exam-room cabinets. The stainless steel material works well visually next to stainless worktops or equipment, creating consistent metal tones across built-ins and storage.
The tight screw pin in this hinge keeps the knuckle stack stable, which helps the hinge maintain its 270 degree free swinging motion without excess play developing between the leaves during daily operation. Elongated holes on both leaves directly affect installation workflow, because they allow the installer to shift the hinge slightly on both door and frame, dialing in reveal lines and overlay depth before tightening the screws. The 0.095 inch (2.4 mm) material thickness supports this adjustment work, since the thicker leaves resist distortion when screws are driven tight against the metal. The frame leaf length of 1-3/4 inches gives a clear reference dimension when laying out multiple hinges on a tall door, helping keep each hinge centered and aligned along the frame edge. With a barrel height of 2-3/4 inches, the knuckle assembly offers a generous vertical bearing area, which spreads load over a taller contact zone and supports consistent alignment on active institutional doors that see frequent opening throughout the day.
The Rockford Process P376-SS is a semi-concealed institutional overlay hinge with a free swinging five knuckle design, so part of the hinge shows while the working knuckles manage wide door motion.
The P376-SS hinge is described as 270 degree screw-on, meaning the hinge geometry allows doors to open to a wide 270 degree arc for clear cabinet access.
The P376-SS hinge is designed for the 32 mm hole system, so it aligns with cabinets drilled on that pattern for consistent hinge spacing along casework sides.
The P376-SS hinge has a frame leaf length of 1-3/4 inches, a barrel height of 2-3/4 inches, and a material thickness of 0.095 inches or 2.4 mm.
The elongated holes on both leaves provide adjustment range, so installers can shift the hinge on door and frame to refine overlay reveals before tightening screws.
This Rockford hinge series is available in five finishes: Gloss Black, Dull Chrome, White, Barrel Brass, and Stainless Steel, letting projects match existing hardware.
The Rockford Process Control P376-SS stainless steel overlay hinge combines a 270 degree free swinging five knuckle design with a semi-concealed institutional profile, making it a strong fit where wide door opening and straightforward appearance are important. With 32 mm hole system design, a 1-3/4 inch frame leaf length, 2-3/4 inch barrel height, and 0.095 inch (2.4 mm) thick stainless steel leaves, the hinge supports demanding cabinet use. The tight screw pin, elongated holes on both leaves, and hospital grade tips bring together alignment flexibility and professional detailing, so this hinge integrates cleanly into institutional, medical, or commercial casework built around overlay doors.
