Rockford Process free swinging overlay hinge is a semi-concealed, free swinging overlay five knuckle hinge designed for institutional applications, so it supports demanding door use where repeated opening and closing is routine. The hinge is classified as an institutional hinge and semi-concealed, which keeps most of the hardware out of sight while still leaving a robust knuckle and barrel for strength at the pivot point. This hinge is designed for the 32 mm hole system, so it integrates into casework and cabinets laid out on that drilling pattern without layout changes. A 270 degree screw-on design allows the door to swing through a wide arc, which gives generous access to the cabinet or casework interior in tight spaces. The dull chrome finish provides a functional, low-glare surface, which suits institutional environments that favor practical, easy-to-match hardware.
This Rockford Process Control P456-26D hinge uses a screw-on mounting style, so it fastens directly to the frame and door and works naturally with common shop tools. The hinge is designed around the 32 mm hole system, which means the mounting locations correspond to standard system holes and support repeatable drilling and hinge positioning on runs of cabinets or institutional casework. Elongated holes on both leaves give lateral adjustment at the frame and door, so the door position can be shifted slightly to fine-tune reveals and alignment after initial screw placement. A tight screw pin holds the five knuckle barrel together firmly, which stabilizes the pivot point and helps maintain consistent alignment once the hinge is set. Together, these details support a straightforward screw-on workflow with room to adjust the door position during final fit-up.
This Rockford Process Control, Inc. hinge is classified as an institutional hinge and hospital grade tips are specified, which positions it for use in environments where hardware is expected to handle frequent operation with a controlled, consistent appearance. The hinge is described as a free swinging overlay five knuckle hinge, so it functions as the primary pivot for overlay doors where no spring closing force is built into the hinge and the door moves freely through its swing. A frame leaf length of 1-3/4 inch defines how far the frame leaf extends onto the frame surface, which dictates where fasteners land and how the load from the door transfers into the frame. Barrel height is 2-3/4 inch, giving a tall knuckle stack that spreads the pivot area over a larger vertical distance, which supports the door along more of its height at the hinge side. Material thickness is specified at 0.095 inch, or 2.4 mm, so each leaf has substantial cross-section to carry shear and bending forces from the door into the frame without relying on very thin metal.
The hinge is designed for the 32 mm hole system, so the mounting layout matches common system drilling jigs and line-boring patterns and helps repeat hinge locations across multiple units, improving consistency from cabinet to cabinet. Elongated holes on both leaves give adjustment at both the frame and the door side, which lets the installer shift the hinge slightly to correct for small drilling or layout variations and set even gaps along the door edges. The tight screw pin keeps the five knuckle barrel closely held, which maintains the relationship between leaves and contributes to a stable pivot that resists loosening under repeated cycles. The 270 degree screw-on configuration allows the door to open through a wide angle, which helps the door clear the opening and provides greater access for loading, cleaning, or servicing inside the cabinet or casework. Availability in both gloss black and dull chrome finishes means the same mechanical specification can be matched to different visual programs, which simplifies hardware standardization across different rooms or wings while keeping finish options open.
The Rockford P456-26D is a semi-concealed, free swinging overlay five knuckle hinge, so it provides an exposed barrel pivot while most mounting surfaces stay out of sight.
The P456-26D is described as a 270 degree screw-on hinge, so it supports a wide door opening arc for increased access to the cabinet or casework interior.
The Rockford Process free swinging overlay hinge is designed for the 32 mm hole system, so its mounting pattern matches standard system drilling layouts.
The hinge has a frame leaf length of 1-3/4 inch, a barrel height of 2-3/4 inch, and material thickness of 0.095 inch or 2.4 mm on the leaves.
Elongated holes on both leaves allow lateral movement of the hinge during installation, which helps fine-tune door position and reveals before final tightening.
The hinge is available in gloss black and dull chrome finishes, so it can be matched to different design schemes while keeping the same hinge specification.
The Rockford Process Control P456-26D dull chrome overlay hinge combines a free swinging overlay five knuckle design with a 270 degree screw-on configuration, so it supports wide-opening doors in institutional casework built on the 32 mm hole system. Hospital grade tips, a 1-3/4 inch frame leaf length, and a 2-3/4 inch barrel height define a hinge built for demanding use where appearance and function both matter. Select this semi-concealed institutional hinge when a dull chrome finish, system-based drilling pattern, and adjustable elongated holes on both leaves are needed to align overlay doors accurately across a project.
