Grass Full overlay Institutional Hinge, 270º Dowel Black - F150145125223

Grass Full Overlay Institutional Hinge For Wide Swing

Grass full overlay institutional hinge is a semi-concealed MB Series barrel hinge that replaces non-adjustable 5 knuckle hinges, so cabinet and casework doors gain clean lines while still meeting institutional demands. The MB Series hinge design provides ease of installation and adjustment, which shortens hinge setup time on repetitive jobs. A wide 270 degree opening angle on full overlay doors allows the door to swing back out of the way, helping carts, equipment, or millwork drawers clear the opening. The Grass America black finish option delivers a dark, uniform appearance that blends into darker casework. The hinge is part of the Grass MB Series system, so it fits projects that standardize on that platform for consistent hardware across a job. Grass America branding and part number F150145125223 clearly identify this specific full overlay black hinge arm for repeat ordering.

Key MB Series Hinge Details For Pros

• Grass MB Series barrel institutional hinge design replaces non-adjustable 5 knuckle hinges, so installers can upgrade to adjustable hardware while keeping a robust institutional hinge layout.
• Tool-less assembly of the hinge arm to the hinge cup lets the door be removable, which speeds hanging and later service when doors need to come off and go back on accurately.
• Height adjustment of plus 2 mm and side to side adjustment of 2 mm allow fine-tuning door edge gaps, reducing rework when aligning multiple doors in a bank.
• The wide 270 degree opening angle on full overlay doors provides generous access to the cabinet interior, which supports institutional use where doors must swing clear.
• Integrated door catch keeps doors in the closed position without additional hardware, which simplifies layout and reduces extra components on each opening.
• Cover caps on all hinge arms conceal mounting screws, giving casework a finished look while still allowing access to adjustments when needed.

Installation, Adjustment, And Hinge Cup Options

Grass MB Series barrel institutional hinges use a 45 mm hinge cup, so casework boring can follow a consistent pattern across doors. Tool-less assembly between the hinge arm and hinge cup lets installers connect or remove doors without tools at that junction, which is useful during finishing or service. The 2 mm height adjustment and 2 mm side to side adjustment provide controlled movement at the hinge, allowing precise tuning of reveals along door edges. Hinge cup and hinge arm are sold separately, with two 45 mm cup options - screw-on and dowelled - so fabricators can match their preferred mounting style. Four types of arms are available in the MB Series, which supports different overlays or applications while keeping the same cup system.

Using This Semi-Concealed Institutional Hinge In Casework

Where This Grass Full Overlay Hinge Is Applied

This semi-concealed institutional hinge from Grass America is part of the MB Series, so it suits projects calling for Grass MB Series barrel hinges instead of exposed 5 knuckle hinges. The full overlay design means the door covers the cabinet front, aligning with modern institutional casework that favors flush, easy-to-clean faces. The 270 degree opening angle allows doors to swing back alongside the case side, helping in locations where doors must not protrude into traffic paths. The hospital tip design on the knuckle gives the hinge a smooth profile at the exposed barrel, well suited to institutional environments that need reduced snag points. Availability in black finish lets shops coordinate with darker laminates or painted finishes, keeping visible hardware visually consistent.

Why Adjustment, Finish, And Rating Matter In Use

The height adjustment of plus 2 mm and side to side adjustment of 2 mm allow precise control of gaps, which is important when aligning long runs of institutional cabinets where uneven reveals stand out. Tool-less hinge arm to cup assembly helps on larger installations because doors can be removed during transport or finishing, then quickly reinstalled without disturbing hinge settings. The integrated door catch holds doors closed without separate catches, reducing layout time and simplifying hardware schedules. Meeting ANSI/BMHA A156.9-2003 Grade 1 hinge requirements indicates this hinge is designed for demanding cabinet applications, which supports use in heavily used institutional casework. The option of screw-on or dowelled 45 mm hinge cups allows the shop to match its machining style, helping maintain production flow across different cabinet lines while still using the same MB Series hinge arms.
