Rockford Process Free Swinging Overlay Five Knuckle Hinge, 270º Screw-on Dull Chrome - P849-26D

Rockford Free Swinging Overlay Hinge For 270 Degree Openings

Rockford Process free swinging overlay hinge is a semi-concealed five knuckle hinge that allows doors to open to 270 degrees, giving wide access to institutional or cabinet openings where full swing is required. The design is classified as a semi-concealed hinge, so part of the hardware is visible while the rest stays out of sight, which helps maintain a clean appearance while still giving a clear view of the pivot points during installation. The hinge is described as hospital grade, which signals a robust style suited to demanding institutional environments where doors cycle frequently. A dull chrome finish is specified, so the surface presents a low-sheen metallic look that helps minimize glare under strong lighting. The hinge is identified as an overlay type, meaning it works in applications where the door overlays the frame instead of sitting flush inside the opening.

Key Overlay Hinge Details For Professional Use

• The hinge is designed for the 32 mm hole system, which helps integrate into casework layouts that follow the standard system drilling pattern used in many commercial and institutional projects.
• A five knuckle configuration is specified, which spreads the pivot movement across multiple knuckles and supports stable motion as the door travels through its 270 degree swing.
• The product is described as free swinging, so the hinge operates without built-in closing mechanisms, giving installers straightforward movement characteristics to coordinate with external door control components.
• The hinge finish is listed as dull chrome, which provides a neutral metallic appearance well suited to institutional interiors where a low-reflective surface is preferred.
• This hinge is categorized under institutional hinges, so it is oriented toward projects where durability and consistent operation under regular use are important selection factors.

Overlay Hinge Mounting And Alignment Characteristics

This Rockford Process semi-concealed overlay hinge is noted as screw-on, so it fastens mechanically to door and frame surfaces using screw connections that allow field positioning within the overlay layout. Both leaves feature elongated holes, which give a bit of lateral adjustment during installation so the door can be shifted slightly before the screws are tightened. The frame leaf length is specified as 1-3/4 inches, giving a defined bearing surface on the frame side that sets how far the hinge extends onto the jamb. A barrel height of 2-3/4 inches is listed, so installers can plan for the vertical dimension of the hinge barrel when aligning multiple hinges along the stile. The material thickness is stated as 0.095 inches, or 2.4 mm, which defines the leaf gauge that affects how the hinge sits between door and frame surfaces.

How This Hospital Grade Overlay Hinge Works In Service

Overlay Hinge Performance In Institutional Settings

This Rockford Process Control P849-26D hinge is categorized as an institutional hinge, so it fits environments such as healthcare or other facilities where doors cycle frequently and hardware needs to maintain alignment under repeated use. The designation as hospital grade highlights that the tip style and overall form are oriented toward medical or similar applications, where consistent performance and clean lines are important. Because this hinge is free swinging, doors move through their travel without self-closing forces from the hinge, which suits layouts where separate door control or hold-open methods are used. The 270 degree opening capability lets doors swing well past 90 degrees, which helps clear wider openings so equipment or carts can move without the door obstructing the passage.

Details That Support Repeatable Alignment And Fit

The semi-concealed construction keeps key working parts near the edge of the door while leaving some hardware visible, which allows installers to visually confirm hinge alignment along the stile. Elongated holes on both leaves add useful fine-tuning capability, since the door position can be shifted slightly during screw-on installation to achieve a more even reveal. The specified 1-3/4 inch frame leaf length gives a consistent reference when laying out hinge positions on the frame, which helps produce uniform spacing from job to job. The 2-3/4 inch barrel height provides a clear dimension for stacking multiple hinges along taller doors so the barrels line up neatly. With a leaf material thickness of 0.095 inch, or 2.4 mm, the hinge presents a defined gauge that supports stable contact between door and frame in typical institutional casework or door assemblies.
