Rockford Process Free Swinging Overlay Five Knuckle Hinge, 270º Screw-on Dull Chrome - P848-26D

Rockford Process Free Swinging Overlay Hinge Function

Rockford Process free swinging overlay hinge P848-26D is a semi-concealed institutional hinge that supports overlay doors while leaving a clean, professional look on the frame. The five knuckle design creates a stable pivot point, which helps doors move in a controlled swing without binding during repeated use. A 270 degree screw-on configuration allows the door to open through a wide arc, which matters when doors need to fold back against the cabinet or frame for clear access. Hospital grade tips add a finished profile at the barrel ends, which helps present a smooth, professional hinge edge in demanding institutional spaces. The hinge is designed for the 32 mm hole system, so it ties directly into casework layouts built on that drilling pattern. As a result, installers can align hinges with existing system holes and keep door margins consistent across multiple openings.

Key Hinge Details That Support Daily Use

• The hinge is classified as a semi-concealed hinge, so only selected portions remain visible, which supports a clean face layout while still allowing access to the knuckle area for inspection or adjustment.
• The five knuckle hinge layout distributes movement across multiple knuckles, which helps the barrel track smoothly over its full swing and supports repeated opening in institutional environments.
• The 270 degree screw-on design allows the door leaf to rotate through a wide opening arc, which is useful when doors must fold back along the case side to keep the doorway clear.
• The hinge is designed for the 32 mm hole system, which lets installers position the screw-on leaves using that familiar grid and maintain consistent reveals on system-based cabinetry.
• The hinge uses hospital grade tips, which form a finished barrel end detail and support institutional applications where a refined hinge tip profile is desired.
• The material thickness is .095 inch (2.4 mm), which gives each leaf substantial section strength for supporting the door weight across the 270 degree swing.

Installation And Alignment Details For This Hinge

This Rockford Process Control hinge is designed for the 32 mm hole system, which means the screw-on leaves locate directly off that drilling pattern during installation. Elongated holes on both leaves provide lateral adjustability, which lets installers fine-tune door position after mounting. A tight screw pin holds the five knuckle barrel together, supporting consistent alignment between door and frame leaves across repeated cycles. The frame leaf length of 1-3/4 inch gives a defined bearing surface along the frame edge, which helps carry the door load into the structure. Barrel height is 2-3/4 inch, which creates a tall pivot profile that spreads stresses over a larger area of the door stile. Together, these details support a hinge setup that can be installed to line up with system drilling while still allowing small field corrections at the screws.

Using This Institutional Overlay Hinge In Projects

Where This Rockford Overlay Hinge Fits Best

This Rockford Process Control, Inc. hinge is categorized as an institutional hinge, which aligns it with cabinets and doors in facilities that rely on robust hardware. As a semi-concealed hinge, it leaves much of the leaf structure out of direct sight lines, which works well for casework where a cleaner exterior is preferred without moving entirely to concealed hardware. The overlay function means the door overlays the frame surface rather than sitting flush within a rabbet, which influences door sizing and the visual reveal around openings. Being designed for the 32 mm hole system, it fits naturally into casework built around that standard drilling grid, which is common in system-based commercial cabinetry. The P848-26D dull chrome finish provides a muted metallic appearance that coordinates with other dull chrome fittings in a project.

Why The Detailed Hinge Design Supports Reliable Results

The five knuckle layout and tight screw pin work together to hold the hinge barrel in consistent alignment, which helps each door swing track repeatably over time. Elongated holes on both leaves let installers shift the hinge position slightly during mounting, which is especially useful when aligning multiple doors along a continuous face. The frame leaf length of 1-3/4 inch offers a defined contact area against the frame edge, which helps distribute door forces into the frame instead of concentrating them at a small point. A 2-3/4 inch barrel height spreads the pivot contact over a taller section, which supports smoother motion across the 270 degree range and helps reduce localized wear. Material thickness of .095 inch, or 2.4 mm, gives the leaves a solid cross-section, which matters when doors are cycled frequently in institutional settings. The dull chrome finish provides a non-reflective metallic surface, which coordinates visually with other dull chrome components while presenting a consistent appearance across hinge barrels and leaves.
