Rockford Process overlay hinge defines this semi-concealed, free swinging overlay hinge built for institutional applications where doors cycle frequently and clear opening is important. The five knuckle design creates a full-length pivot that spreads the load across multiple knuckles, which supports smoother door motion on framed casework or cabinets. Hospital grade tips at the ends of the hinge barrel shape the profile for environments that call for this specific style, giving facilities a consistent look from opening to opening. A barrel height of 2-3/4 inches sets a substantial vertical bearing surface, which helps the hinge track the door edge predictably over time. Material thickness of .095 inch, or 2.4 mm, gives the leaves a solid cross-section, so the hinge resists flexing during operation on heavier institutional doors. The gloss black finish provides a dark, uniform appearance that blends with black doors or trim.
The hinge is designed for the 32 mm hole system, so it matches casework that follows this standardized drilling pattern and lets installers work directly with line-bored cabinet sides and frames. Both leaves use screw-on mounting, which means the hinge fastens through its holes into the door and frame surfaces so it can be positioned using standard drilling equipment. Elongated holes on both leaves give adjustment room in the screw pattern, allowing the door to shift slightly during final tightening to dial in alignment across multiple hinges on a run of cabinets. The frame leaf length of 1-3/4 inches sets how far the hinge extends along the frame, helping installers visualize hinge spacing on tall doors or along wider frames.
This hinge sits in the institutional hinges class as a semi-concealed design, so part of the hardware is visible while critical working surfaces sit between the door and frame. The five knuckle layout runs along the barrel height of 2-3/4 inches, which gives the door a stable pivot for taller or heavier doors that still need free swinging movement. The hospital grade tips finish off each end of the barrel, which suits projects calling for this specific tip geometry on exposed hinge barrels across a facility. Because the hinge is designed for the 32 mm hole system, it lines up with casework that uses this system spacing, helping maintain consistent hinge locations door to door. The gloss black finish gives the installation a dark, uniform appearance, useful when matching other black hardware or dark casework components in the same room.
The free swinging overlay design allows the door to travel through its arc without an integrated stop, which is important when a door must move fully out of the way for clear access to medical, storage, or equipment cabinets. With 270 degree screw-on capability, the door can rotate well beyond standard right-angle openings, so users can open doors along walls or casework ends without blocking adjacent access. The .095 inch, or 2.4 mm, material thickness gives the hinge leaves mass, which helps the knuckles and tight screw pin carry door weight through repeated cycles. Elongated holes on both leaves add adjustment range around the 32 mm system mounting points, which helps fine-tune reveals across banks of doors after initial screw placement. The combination of institutional hinge classification and hospital grade tips supports projects that need a consistent hinge style across multiple openings, keeping the visual and functional hardware choice the same throughout the installation.
The P376-1D is a semi-concealed, free swinging overlay hinge with a five knuckle design, so part of the hinge is visible while the door overlays the frame for institutional casework.
The hinge is a 270 degree screw-on style, so it allows the door to rotate up to 270 degrees, helping the door swing well past 90 degrees for wider access.
The hinge is designed for the 32 mm hole system, so it works with casework that follows this pattern and keeps hinge positions aligned with line-bored cabinet construction.
The elongated holes on both leaves provide adjustment room during screw-on mounting, allowing the door position to shift slightly for improved reveals and alignment.
The hinge has a barrel height of 2-3/4 inches and a frame leaf length of 1-3/4 inches, giving defined bearing surfaces that support consistent mounting on the frame.
The hinge is available in gloss black, dull chrome, white, barrel brass, and stainless steel, so finish can be selected to coordinate with surrounding casework and hardware.
This Rockford Process Control, Inc. free swinging overlay hinge combines a five knuckle barrel, 270 degree screw-on movement, and hospital grade tips, so it suits institutional hinges projects that follow the 32 mm hole system. The .095 inch, or 2.4 mm, material thickness and tight screw pin create a solid pivot, while elongated holes on both leaves support fine adjustment during mounting. For casework needing gloss black hardware with a semi-concealed overlay look, this P376-1D hinge aligns visual style with practical mounting and swing performance.
