Sugatsune center hinge 180 degree describes a semi-concealed hinge from Sugatsune America that is designed as a center hinge for folding doors. The 180 degree opening allows the connected folding door leaves to swing fully open, which keeps the opening clear for better cabinet or closet access. The hinge snaps in at both the open and closed position, so the folding door can hold firmly when closed and stay put when folded back, reducing door drift during everyday use. As a semi-concealed hinge in the Semi-Concealed Hinges product class, it leaves part of the hardware visible while the rest is hidden, which keeps alignment accessible while maintaining a cleaner finished look on a face-frame cabinet. The hinge is finished in nickel, giving it a neutral metallic appearance that suits common hardware finishes on folding door layouts.
This Sugatsune America semi-concealed center hinge is identified for folding doors and categorized under Semi-Concealed Face-Frame Hinges, which positions it for use on face-frame constructions where a center hinge controls the break between panels. The hinge uses a screw-on style, as described in the product name, so the leaves are fastened with screws through the four holes provided in the hinge, allowing the installer to draw the hinge tight to the mounting surfaces. The 2-15/16 reference in the SAP description, CENTER HINGE-FOLDING DOORS 2-15/16 NKL, indicates a size dimension that helps match this CH-75/NI hinge to the intended door geometry. With three knuckles in the hinge design, the pivot is supported along multiple bearing points, which guides the folding action smoothly through the full opening arc.
The CH-75/NI center hinge is described specifically as a center hinge for folding doors, making it suitable where two door panels meet and need a controlled pivot between them. Its categorization under Semi-Concealed Face-Frame Hinges connects it to face-frame cabinet or similar structures that carry folding door pairs. The 2-15/16 measurement in the SAP description gives a defined size point for planning the spacing of folding leaves so that the hinge aligns with the door edges and frame layout. With three knuckles, the hinge establishes a stable pivot line, which is useful when the center joint must carry the load of two narrow panels swinging together. The nickel finish allows it to sit visually with other nickel-based components in the same installation, keeping the hinge appearance consistent at the fold line.
The 180 degree opening capability of this Sugatsune center hinge lets folding doors travel through a wide swing, which keeps the panels from crowding the opening and gives more working space in front of face-frame cabinetry. The snap-in action at the closed position provides a distinct holding feel at shut, which helps the panels register where they belong against adjacent components. The snap-in action at the open position also keeps the folding doors stable when they are folded back, so the doors resist drifting toward partially open positions while work is being done at the opening. The screw-on identification means the hinge is secured by screws through four holes, which distributes the load at the mounting points along the leaf. Being part of Sugatsune Americas Semi-Concealed Hinges product class, the CH-75/NI hinge combines partial concealment with accessible hinge geometry, supporting repeatable alignment and functional folding action.
The CH-75/NI hinge is a center hinge for folding doors, so it connects door panels at the fold line where two leaves meet and pivot together.
The hinge provides 180 degree opening, allowing folding door leaves to swing fully open so the doorway remains clear during access or work inside the cabinet.
The hinge is in the Semi-Concealed Hinges class, so part of the hardware is visible while other portions are hidden, balancing appearance with access to the hinge area.
The hinge snaps in at open and closed positions so folding doors hold more firmly when shut and stay more stable when folded back to the fully open position.
The 2-15/16 reference in the SAP description indicates a size dimension used when planning hinge placement and door geometry for folding door layouts.
The hinge has three knuckles and a 180 degree opening, providing multiple bearing points and a wide swing that support controlled, smooth folding door movement.
The Sugatsune center hinge 180 degree design, identified as CH-75/NI and CENTER HINGE-FOLDING DOORS 2-15/16 NKL, brings 180 degree opening, snap-in open and closed positions, and three knuckles to folding door applications. As a semi-concealed hinge in a nickel finish within the Semi-Concealed Face-Frame Hinges category, it aligns with face-frame folding door layouts where appearance and access to the hinge line both matter. For projects calling for a defined center hinge at the fold between door panels, this part number provides a clearly specified option for planning the hardware pattern across the installation.
