Rockford Process Free Swinging Overlay Five Knuckle Hinge, 270º Screw-on Gloss Black - P456-1D

Rockford Process Free Swinging Overlay Hinge Purpose

Rockford Process free swinging overlay hinge provides a semi-concealed, five knuckle solution that swings to 270 degrees, so doors can open wide for clear access in institutional and cabinet applications where full opening is important. The hinge is designed for the 32 mm hole system, which aligns with common European-style boring patterns, helping installations match existing casework layouts in shops using that drilling standard. A gloss black finish on this hinge delivers a dark, uniform look, useful when hardware needs to blend with darker casework or fixtures in a room. Hospital grade tips on the hinge give a smooth, finished end to the knuckles, which supports use in healthcare or institutional environments that favor closed, clean hardware profiles for daily operation. The semi-concealed design places part of the hinge out of sight, which keeps the focus on the door face while still presenting a robust knuckle at the edge.

Key Overlay Hinge Details For Daily Use

• The five knuckle configuration provides multiple bearing points along the barrel, which supports smooth free swinging motion of the door and consistent alignment over repeated opening cycles on institutional casework.
• The 270 degree opening capability allows the door to fold back farther against the cabinet or frame, which helps keep the door out of the way in tight corridors or workspaces where clearance matters.
• The design for the 32 mm hole system lets installers match hinge positioning to pre-bored patterns, which speeds layout and helps keep hinge rows consistent across banks of cabinets or institutional fixtures.
• The gloss black finish gives the hinge a dark, reflective surface, which visually ties in with black or dark-toned doors and frames and supports a coordinated look on visible hardware installations.
• Hospital grade tips create a closed end on the barrel, which avoids exposed cut edges on the hinge knuckles and presents a more finished edge at the hinge side of the door.
• The semi-concealed classification indicates part of the hinge is hidden when the door is closed, which lets projects use a functional institutional hinge while reducing visible hardware on the door face.

Screw-On Overlay Hinge Fit And Mounting

This 270 degree screw-on gloss black hinge uses a screw-on mounting method, so the leaves fasten directly to the frame and door with mechanical fasteners for a solid attachment on institutional casework and cabinetry. The frame leaf length is 1-3/4 inches, giving a defined bearing surface on the frame side that supports the door weight along a known dimension during layout. Elongated holes on both leaves offer lateral adjustment at installation, so the door can be shifted slightly before tightening to achieve a more even gap and alignment with adjoining doors. A tight screw pin holds the five knuckle barrel together, which keeps play in the knuckles limited for more controlled swing and consistent reveal. Barrel height is 2-3/4 inches, providing a taller hinge profile that spreads load along the edge of the door, while the material thickness of 0.095 inches, or 2.4 mm, gives the leaves a solid section for institutional service.

Using This Semi-Concealed Institutional Hinge On Projects

Where This Rockford Process Hinge Fits Best

This Rockford Process semi-concealed hinge is categorized as an institutional hinge, aligning it with applications such as healthcare, education, or other commercial casework that benefit from hospital grade tips and robust five knuckle construction. The gloss black finish lets this hinge blend into darker cabinets or frames, which suits environments where visible hardware should coordinate closely with the color scheme instead of standing out. Because the hinge is designed for the 32 mm hole system, it integrates well with casework built around that modular drilling pattern, so rows of hinges can be positioned consistently across multiple doors. The frame leaf length of 1-3/4 inches supports use on frames or carcasses that offer enough flat bearing surface, giving installers a clear reference dimension when laying out hinge spacing and edge distance. As a semi-concealed hinge, it works well when projects require visible institutional knuckles yet want less hardware on the door face.

Details That Support Alignment And Repeatable Results

The tight screw pin in this five knuckle hinge helps hold the barrel components firmly together, giving doors a controlled swing that aids in maintaining uniform reveals along banks of cabinets over time. Elongated holes on both leaves provide useful adjustment during installation, so minor shifts can be made to pull door edges into line without redrilling, which helps reduce rework on multi-door runs. The 270 degree opening capability supports repeatable access in service areas where doors are routinely folded back, helping them rest flat and reducing the chance of partially open doors obstructing flow. Barrel height at 2-3/4 inches spreads forces along a taller section of the door edge and frame, which supports alignment when multiple hinges of the same size are stacked on a tall door. Material thickness of 0.095 inches, or 2.4 mm, gives the leaves a substantial feel, supporting stable screw holding and hinge integrity under frequent institutional use.
