1131 Invisible 180˚ Opening Hinge, Matte Black

1131 Invisible 180 Degree Opening Hinge Purpose

1131 invisible 180 degree opening hinge describes a concealed hinge designed to open a door a full 180 degrees, so the door can swing completely clear of the opening for maximum access in use. The hinge belongs to the invisible hinges product class, which means the hardware stays hidden when the door is closed, supporting clean cabinet and door faces on visible projects. A matte black finish gives the hardware a dark, recessive look in the gap, which helps it disappear visually next to darker doors and frames. The hinge is manufactured in zinc to resist oxidation, so the hinge body is built for normal interior environments where corrosion resistance supports long service life. The product is UL certified, so it has been evaluated against defined performance standards that matter on commercial and higher-spec jobs.

Key Working Details Of The Matte Black Hinge

• The hinge is suitable for doors with a minimum thickness of 1-1/2 inches, so it matches heavier, thicker doors rather than thin cabinet fronts and keeps the pivot geometry stable on substantial doors.
• It is rated for doors up to 39-3/8 inches wide, so it is designed to carry wider door leaves within its tested load capacity without over-stressing the concealed mechanism.
• A stated load capacity of 265 lb (120 kg) means each hinge is engineered for heavy-duty door applications, so installers can apply it on substantial doors where structural support is critical.
• The hinge offers easy 3D adjustment, giving vertical, horizontal, and depth fine-tuning at the hardware, so alignment tweaks can be done at the hinge rather than reworking the door or frame.
• The hinge has a fluid 180 degree opening characteristic, so the door movement is designed to be smooth across the full swing, which supports precise positioning against adjacent panels and walls.
• Testing for a minimum of 200,000 opening and closing cycles means the hinge has been cycled repeatedly under load, so it is built for long-term, repeated use in doors that see frequent operation.

Installation And Mortising Details For This Hinge

The hinge is designed for easy installation with symmetrical mortising for both the door and the frame, so the same routing pattern can be used on each side to speed layout and reduce chance of mirrored errors. Symmetrical mortising also keeps the hinge geometry consistent between leaf and jamb, which supports accurate alignment when multiple hinges are fitted on one door. Being an invisible hinge, the product fits into recesses rather than surface mounting, so the door edge and frame must be cut to accept the hinge body while preserving clean exterior faces. The load capacity of 265 lb works together with the specified door thickness and width range, so hinge spacing and count can be planned around a heavy door without overloading individual hinge points.

Applications For 1-1/2 Inch Thick Doors

This hinge is suitable for doors with a minimum thickness of 1-1/2 inches, so it aligns with thicker cabinet doors, passage-style doors in built-ins, and heavy specialty panels where a standard thin-door hinge would not seat correctly. A maximum recommended door width of 39-3/8 inches frames where this hinge is intended to work, so it fits single-door sections that need generous width without moving into oversized door hardware. The invisible hinge design keeps all moving parts recessed into the door and frame, which supports a clean appearance on flush or minimal installations. The matte black finish suits dark painted or stained doors, so any visible gap hardware blends into the shadow line rather than drawing attention at the edge.

Adjustment, Durability, And Long-Term Alignment

The hinge provides easy 3D adjustable capability, so after the door is hung, the installer can fine-tune vertical height, horizontal gap, and depth inset directly at the hinge to correct for small layout differences. This adjustability supports consistent reveals between the door and frame, which reduces rework when multiple hinges must align on one leaf. A load capacity of 265 lb (120 kg) means the internal linkage and body are built for significant weight, so the hinge can support heavy doors without sagging under rated conditions. Testing for a minimum of 200,000 opening and closing cycles indicates the mechanism has been proven through repeated motion, which is important where the door will be used frequently over many years. The zinc construction resists oxidation, so the hinge body is protected from typical indoor moisture, which helps maintain smooth movement. Fluid 180 degree opening means the action stays even from closed to fully open, so doors can rest against adjacent walls or panels at full swing without abrupt stops, supporting predictable clearances on site.

Common Questions About This Invisible Hinge

Selecting This Hinge For Heavy, Concealed Doors

The Peter Meier 1131 invisible 180 degree opening hinge in matte black combines a 265 lb load capacity with suitability for 1-1/2 inch thick doors up to 39-3/8 inches wide, so it targets heavy, concealed applications. Easy 3D adjustment and symmetrical mortising streamline fitting and alignment, while zinc construction, UL certification, and testing to 200,000 cycles support long-term performance. For projects that require a full 180 degree opening swing with concealed hardware and a dark, recessive finish, this hinge provides the functional details needed for precise, repeatable installations.
