Grass Self-Close Full overlay Institutional Hinge, 270º Screw-on Nickel - F150000014223

Grass MB Series Barrel Hinge For Institutional Use

Grass MB Series barrel institutional hinge gives installers a semi-concealed option that replaces non-adjustable 5 knuckle hinges, so casework can have a cleaner look while still meeting demanding institutional requirements. This Grass self-close full overlay institutional hinge is designed around a wide 270 degree opening angle, allowing doors to swing back clear for full access to cabinet interiors or equipment. The hinge works with a 45 mm hinge cup, so layouts can follow a consistent boring pattern across a project. The product is Bright Nickel Plated, which presents a neutral, professional finish that works with common commercial hardware palettes. As part of the MB Series, the hinge is built for applications where appearance, accessibility, and adjustment all matter on day one and during later service work.

Key Hinge Details That Support Daily Use

• Grass MB Series barrel institutional hinges are described as a great alternative to non-adjustable 5 knuckle hinges, so installers can keep a familiar institutional duty level while moving to a more streamlined semi-concealed layout.
• Tool-less assembly of the hinge arm to the hinge cup allows the door to be removable, so doors can be taken off and reinstalled quickly during fabrication, finishing, or later service without disassembling the entire hinge system.
• The hinge offers a wide 270 degree opening angle on full overlay doors, so doors can clear the opening and sit out of the work path in labs, shops, and other high-traffic institutional environments.
• Hinges have a height adjustment of plus 2 mm and side to side adjustment of 2 mm, so installers can fine-tune reveal and edge gaps to keep door lines consistent across a bank of cabinets.
• All hinge arms have cover caps to conceal mounting screws, so visible hardware points are hidden and the finished installation presents a cleaner, more professional appearance in institutional settings.
• The knuckle features a hospital tip design, so exposed hinge ends present a smoother profile that aligns with typical institutional hardware expectations for safety and clean lines.

Installation And Adjustment Details For This Hinge

This Grass self-close full overlay institutional hinge is part of a system where the hinge cup and hinge arm are sold separately, so installers can select from screw-on or dowelled 45 mm hinge cups to match their preferred drilling and fastening process. Tool-less assembly of the hinge arm to the hinge cup means the arm locks to the cup without tools, which speeds door hanging and simplifies removal when doors need to be taken down for finishing or repair. A height adjustment of plus 2 mm and side to side adjustment of 2 mm give enough movement to align door edge gaps and compensate for small drilling or case-tolerance variations. The full overlay geometry combined with the 270 degree opening angle supports layouts where doors need to clear wide case openings while still closing flush over the cabinet front.

How This Semi-Concealed Institutional Hinge Performs

Where This Grass Institutional Hinge Works Best

This hinge is categorized as a semi-concealed institutional hinge, so it is suited to projects that need a cleaner look than a 5 knuckle butt hinge while still functioning in institutional environments. The Grass MB Series barrel institutional hinge has a wide 270 degree opening angle on full overlay doors, which fits casework where full interior access is required, such as storage cabinets, utility closets, or work-area bases. Its Bright Nickel Plated finish pairs well with other nickel-toned pulls and closers often used in commercial and institutional millwork. The hinge meets ANSI/BMHA A156.9-2003 Grade 1 hinge requirements, aligning it with high-duty cabinet hardware standards that are common in schools, healthcare, or public facilities where doors see frequent use.

Why The Hinge Design Supports Repeatable Results

The MB Series hinge uses tool-less assembly of the hinge arm to the hinge cup, which simplifies production runs because doors can be quickly snapped on or off during staging, reducing handling time when working through large batches. With hinge cups in a standard 45 mm size and separate screw-on or dowelled options, boring and installation can follow consistent jigs while still allowing shops to choose their preferred fastening style. A height adjustment of plus 2 mm and side to side adjustment of 2 mm allows small corrections after the case is installed, so door reveals can be tuned without reboring or shifting the cabinet. The integrated door catch keeps doors in the closed position without additional hardware, reducing the number of components on the door edge and helping maintain a tidy appearance over the life of the installation. Cover caps on the hinge arms conceal mounting screws, creating uniform sightlines along door edges. The hospital tip design on the knuckle provides a smooth, finished profile that aligns visually with other institutional-grade components while maintaining the semi-concealed character of the hinge.
