Rockford Process Free Swinging Overlay Five Knuckle Hinge, 270º Screw-on Dull Chrome - P454-26D

Rockford Free Swinging Overlay Hinge For Cabinets

Rockford Process free swinging overlay hinge provides a 270 degree screw-on action that lets doors swing through a wide arc, which helps when cabinets or institutional doors need generous opening clearance. This five knuckle hinge is a semi-concealed institutional hinge, so most of the working hardware stays out of sight while still handling frequent door movement. The hospital grade tips are designed for institutional environments where smooth tips are preferred around staff, patients, or passersby. The barrel height of 2-3/4 inches creates a substantial pivot point, supporting the overlay door as it travels through its full swing. Material thickness of .095 inches, or 2.4 mm, gives the leaves a solid feel that supports repeated cycles. The dull chrome finish offers a neutral, professional appearance that works well in many medical or commercial interiors.

Key Overlay Hinge Details That Support Work

• The 270 degree screw-on design lets the door open wide past typical angles, which is useful when carts, equipment, or large items need better access to cabinet interiors.
• The hinge is designed for the 32 mm hole system, so it works with cabinet layouts that follow this drilling standard often used in institutional and commercial casework.
• The frame leaf length of 1-3/4 inches provides a defined bearing surface on the frame, which helps distribute loads along the stile or frame edge.
• The tight screw pin holds the five knuckle joint closely together, which supports consistent door alignment as the hinge cycles in high-use locations.
• Elongated holes on both leaves allow fine positioning during screw-on installation, which helps align reveals and brings doors into line with adjacent fronts.
• The dull chrome finish option provides a subdued metallic look that coordinates with many hardware choices in medical and commercial spaces.

Overlay Hinge Mounting And Adjustment Details

This semi-concealed hinge uses a screw-on mounting method, so it fastens directly through the leaves into the frame and door, which suits on-site installation or replacement work. Because the hinge is designed for the 32 mm hole system, it aligns with rows of system holes commonly drilled in cabinet sides and frames, supporting repeatable positioning across a run. The elongated holes on both leaves give room to shift the hinge slightly during fastening, which helps refine gaps and overlay lines without redrilling. With a frame leaf length of 1-3/4 inches and a barrel height of 2-3/4 inches, the hinge establishes a consistent pivot reference, so multiple hinges on the same door share the same geometry. This geometry supports smoother swinging through the full 270 degree arc.

Using This Semi-Concealed Institutional Overlay Hinge

Where This Dull Chrome Overlay Hinge Fits

This hinge is categorized as a semi-concealed institutional hinge, so it suits projects where much of the hardware is kept discreet while still supporting frequent door use. The design for the 32 mm hole system fits cabinet and casework builds that follow this drilling pattern, which is common in modular and system-based layouts. With its hospital grade tips, the hinge is well suited to hospital or similar institutional environments where hinge ends need a smooth profile along the barrel. The dull chrome finish presents a clean, low-glare appearance that works in medical, lab, or commercial corridors, allowing doors and cabinets to blend into professional surroundings. As an overlay hinge, it supports doors that overlap the frame, which is a frequent construction in institutional cabinetry.

Why This 270 Degree Hinge Supports Consistent Results

The 270 degree screw-on design lets the door swing through a wide opening range, which can make access to shelves and stored items more straightforward in tight service rooms. The five knuckle configuration creates a stable pivot for that wide motion, helping the door track smoothly along the barrel height of 2-3/4 inches. Material thickness of .095 inches, or 2.4 mm, gives each leaf substance, which supports the door as it is opened and closed repeatedly in institutional settings. Tight screw pin construction helps the knuckles stay closely aligned over time, which supports consistent door positioning. Elongated holes on both leaves give the installer lateral adjustment during fastening, which helps set uniform reveals on multi-door runs. The frame leaf length of 1-3/4 inches adds bearing area to the frame contact, distributing forces as the door cycles across the full swing.
