Grass Half overlay Institutional Hinge, 270º Screw-on Nickel - F150000015223

Grass Half Overlay Institutional Hinge For Wide Swing

Grass half overlay institutional hinge gives institutional and cabinetry doors a 270 degree opening angle on full overlay layouts, so doors can swing back out of the way in high-access areas. This hinge is part of the Grass MB Series barrel institutional hinges, which serve as an alternative to non-adjustable 5 knuckle hinges and change the installation process by relying on concealed mechanics instead of exposed knuckles. As a semi-concealed hinge, it keeps the working hardware largely out of sight while still allowing practical access to mounting points, which helps projects needing a clean appearance around door edges. The nickel plated finish on this hinge provides a bright, consistent surface that visually matches other nickel hardware in the same environment. The hinge is identified by manufacturer part number F150000015223, giving shops and facilities a clear reference when standardizing on a specific hinge across multiple openings.

Key Grass MB Series Hinge Working Advantages

• 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 without using tools during fitting or later service.
• Height adjustment of plus 2 mm lets installers fine-tune vertical door position, which helps align door tops and bottoms across a run of cabinets or casework.
• Side-to-side adjustment of 2 mm gives lateral movement at the hinge, helping dial in even door edge gaps and reduce rubbing along the cabinet or frame.
• Wide 270 degree opening angle on full overlay doors provides generous access into the cabinet or opening, which can improve usability in institutional and high-traffic installations.
• Integrated door catch keeps doors in the closed position without additional hardware, simplifying the opening by using the hinge to hold the door shut.
• Hospital tip design on the knuckle shapes the exposed end for institutional use, which supports applications where that style of hinge tip is required.
• Grass MB Series barrel institutional hinge design replaces non-adjustable 5 knuckle hinges, giving projects adjustment features that can reduce rework during punch-out.

Screw-On Hinge Arm And Adjustment Details

The hinge arm on this Grass MB Series part is designed as a screw-on style, so it fastens mechanically to the matching hinge cup during installation. The hinge system uses a 45 mm hinge cup, giving a defined interface size for drilling door preparations. Tool-less assembly of the hinge arm to the hinge cup allows the door to be removable, which speeds up finishing, transport, and on-site adjustment when doors need to come off temporarily. Once installed, the hinge provides a height adjustment of plus 2 mm and a side-to-side adjustment of 2 mm, so installers can shift doors vertically and laterally using the hinge hardware rather than altering the casework. These built-in adjustments help create consistent reveals and limit callbacks related to door alignment.

Using This Semi-Concealed Institutional Hinge In Projects

Where This Grass Half Overlay Hinge Fits Best

This Grass half overlay institutional hinge functions as a semi-concealed hinge in institutional hinges applications, giving a cleaner look than traditional 5 knuckle institutional hinges while keeping robust hardware at the door edge. The wide 270 degree opening angle on full overlay allows doors to open back out of the way, which suits cabinets and enclosures where full interior access is important. Its role as a Grass MB Series barrel hinge positions it as an alternative to non-adjustable 5 knuckle hinges, making it suitable for projects that want institutional-grade hardware with adjustment built into the hinge. The hinge meets ANSI/BMHA A156.9-2003 Grade 1 hinge requirements, so it aligns with projects that specify that performance level for institutional hardware. Bright nickel plated finish gives a consistent appearance that pairs with other nickel hardware within the same facility or casework lineup.

Details That Support Alignment And Repeatable Results

The Grass MB Series barrel institutional hinge system uses a hinge cup and hinge arm arrangement, with the hinge cup at 45 mm and the arm connecting by tool-less assembly, so installers gain a repeatable drilling pattern and a predictable mounting interface. Tool-less arm attachment means the door is removable, which simplifies adjusting reveals because the same arm can be detached and reattached without disturbing the base mounting. Height adjustment of plus 2 mm offers fine control over how the door sits relative to neighboring doors, helping align rows across long institutional runs. Side-to-side adjustment of 2 mm gives additional tuning at each hinge position, making it easier to correct small layout variations in carcasses or frames. The integrated door catch keeps doors in the closed position without additional hardware, which reduces separate components influencing gap settings. The hospital tip design on the knuckle provides a finished end detail expected in institutional environments, supporting consistent results where that profile is part of a project standard.
