Rockford Process Free Swinging Overlay Five Knuckle Hinge, 270º Screw-on Dull Chrome, 50/Pairs, 456-26D

Rockford Process Overlay Hinge For 32 Mm Systems

Rockford Process overlay hinge is a semi-concealed institutional hinge designed around the 32 mm hole system, so it integrates with cabinet layouts that follow that drilling pattern and keeps hole alignment straightforward across multiple doors. The hinge is identified as a free swinging overlay five knuckle design with a 270 degree screw-on configuration, which allows wide door travel while the knuckle stack manages the pivot smoothly around the frame. As a semi-concealed hinge in the institutional hinge category, it leaves only the key working geometry visible when the door is closed, which keeps the door face cleaner while still giving access to the hinge for service. The hospital grade tips are built into this design, so the ends of the barrel provide a smoother profile along the hinge edge that suits healthcare and similar environments where snag points are a concern.

Key Overlay Hinge Details That Support Projects

• The 32 mm hole system orientation means this hinge fits casework built on that standard, which helps installers line up bore patterns and repeat the same measurements across runs of cabinets.
• The overlay five knuckle layout distributes movement through several knuckles, which supports consistent swing characteristics along the full 270 degree arc for doors that need a wide opening path.
• The free swinging operation lets the hinge move through its travel without an internal stop, which keeps the motion predictable when doors are opened fully against nearby walls or casework.
• The hospital grade tips at the ends of the hinge barrel provide a shaped terminal detail, which suits institutional installations that prioritize smoother hardware edges along high-traffic door lines.
• The semi-concealed hinge classification means portions of the hardware remain recessed when the door is shut, which maintains a more streamlined appearance while still exposing enough of the hinge for adjustment work.

Overlay Hinge Mounting And Screw-On Fit Details

The 270 degree screw-on configuration describes how this hinge attaches to the cabinet and door surfaces, so the installer fastens it in place with screws rather than relying on press-in or weld-on methods. The frame leaf length of 1-3/4 inch defines the coverage along the frame edge, which gives a known bearing surface when laying out screw positions at the stile. Elongated holes on both leaves are part of the design, so there is room to shift the hinge slightly during installation to adjust door alignment without redrilling. The barrel height of 2-3/4 inch sets the vertical dimension of the knuckle stack, which helps plan clearances where multiple hinges share space on a tall door.

Using This Semi-Concealed Hinge In Institutional Work

Where This Semi-Concealed Institutional Hinge Fits

This hinge sits in the institutional hinges category, so it is aimed at projects where casework sees regular use, such as healthcare or similar facilities that value hospital grade tips and a semi-concealed profile. The overlay configuration positions the door over the cabinet frame, which is common in frameless and many framed layouts built on the 32 mm hole system, so the hinge supports that cabinet style. Material thickness is listed at .095 inch, or 2.4 mm, which provides a substantial leaf section that suits frequent door cycling in busier environments. The hinge is available in dull chrome, matching the HINGE, DULL CHRM OVERLAY description, so it can coordinate with other dull chrome hardware for a consistent hardware finish line.

Details That Help Achieve Consistent Door Results

The tight screw pin is a specific detail of this hinge, and it holds the knuckle stack together with limited play, which supports repeatable door alignment and reduces movement at the joint over normal use. Elongated holes on both leaves work with that tight pin by allowing fine shifts in position before screws are fully driven, so doors can be trued to neighboring fronts and frames without opening new holes. The 270 degree free swinging travel lets the door open past a standard right-angle swing, which gives more access into the cabinet interior where full access is valuable. The five knuckle configuration spreads the pivot over more contact points, which supports smooth movement throughout that 270 degree range and helps manage the load across the hinge height.
