Grass Institutional Hinge, Dowel Black - F150145124233

Grass MB Series Barrel Institutional Hinge Use

Grass MB Series barrel institutional hinge gives installers an alternative to non-adjustable 5 knuckle hinges by using a semi-concealed hinge layout, which helps deliver a cleaner door appearance while preserving the robust motion needed in institutional environments. The hinge design offers ease of installation, adjustment, and a clean look, so doors can be fine-tuned after mounting instead of relying on exact drilling alone. This hinge works within the Grass MB Series system, so it fits projects where an institutional hinge is required but a more streamlined visual result is preferred. As a semi-concealed hinge, it hides more of the working hardware, which supports designs that need institutional durability without a fully exposed knuckle at the door edge.

Key Functional Details For Institutional Projects

• The wide 270 degree opening angle on full overlay lets doors swing far out of the way, which helps users access cabinet interiors without the door blocking the opening during service or daily use.
• The hinges have a height adjustment of plus 2 mm, allowing small vertical corrections after mounting so door reveals line up without redrilling hinge locations.
• The side to side adjustment of 2 mm supports precise door edge gap tuning along the width, helping achieve consistent spacing across multiple doors in a run.
• Tool-less assembly of the hinge arm to the hinge cup allows the door to be removable, so doors can be taken off quickly for finishing, transport, or repair and then reattached without tools at the cup connection.
• The integrated door catch keeps doors in the closed position without additional hardware, which reduces the number of components needed on the cabinet while still holding the door shut.
• The knuckle features a hospital tip design, which shapes the exposed hinge end to institutional preferences where this profile is required or desired.

Installation And Dowelled Hinge Cup Interface

This institutional hinge uses a dowelled hinge cup in a 45 mm size, so the cup locates in predrilled dowel holes while the 45 mm diameter defines the cup bore required in the door. The hinge cup and hinge arm are sold separately, so installers choose the correct cup and arm style from the MB Series offering to match their construction. Two types of hinge cups are available in the MB Series, screw-on and dowelled, and this cup style is the dowelled version, which suits shop workflows set up for dowel insertion and press-fitting. Four types of arms are available within the MB Series system, giving layout flexibility around overlay and application while still using the same 45 mm institutional cup interface.

Why This Grass Institutional Hinge Fits Demanding Use

Institutional Hinge For Semi-Concealed Applications

This Grass semi-concealed institutional hinge shifts from a traditional 5 knuckle exposed layout to a barrel-style hinge that tucks much of the hardware out of direct sight, which suits institutional cabinets needing a cleaner look. Grass MB Series barrel institutional hinges are described as a great alternative to non-adjustable 5 knuckle hinges, so they support similar heavy-use environments while offering adjustment that fixed knuckle hinges lack. The hinge operates as part of the MB Series system, and all hinge arms are supplied with cover caps to conceal mounting screws, which keeps visible fasteners hidden behind a finished cap after installation. That cover cap detail helps projects that specify an institutional hinge but still expect refined hardware presentation along door edges and frames. Available finishes in the MB Series include Bright Nickel Plated or Black, and this model is described as black, so it suits darker hardware schemes or applications where a black hinge presence is preferred around the door corner.

Adjustment, Opening Angle, And Performance Rating

The hinge provides a wide 270 degree opening angle on full overlay, letting the door swing back alongside the cabinet so the opening remains largely unobstructed for access and maintenance tasks. Height adjustment of plus 2 mm on the hinge lets installers shift the door vertically after mounting, which is useful for aligning doors in banks where slight drilling tolerances can otherwise stack into noticeable misalignment. Side to side adjustment of 2 mm allows the door to move horizontally at the hinge, fine-tuning the reveal so the door edge gap looks consistent from top to bottom. The tool-less assembly of the hinge arm to the hinge cup not only lets the door be removable, it also speeds on-site door hanging because the arm clips to the cup without using tools at that interface. The hinge features an integrated door catch that holds the door in the closed position, simplifying layouts that do not require separate catches on the cabinet. This institutional hinge meets ANSI/BMHA A156.9-2003 Grade 1 hinge requirements, which indicates a performance level aligned with demanding institutional or commercial cabinet use where life-cycle testing and strength criteria matter. Working within the MB Series structure, installers can select from four types of arms while using this dowelled 45 mm cup, tying together adjustability and rated performance in a coordinated system.
