Center hinge folding doors bronze describes this Sugatsune CH-75/GB semi-concealed hinge, designed to support folding door layouts where a center pivot is required. The 180 degree opening lets the connected doors swing fully open, which gives clear access across the opening and helps prevent door edges from clashing in normal use. The hinge snaps in at both the open and closed positions, providing positive detents that help hold doors where they are set and reduce unintended movement from light bumps. This hinge is a screw-on style, so it mounts using standard screw-driving tools and fits workflows that rely on mechanical fastening. The bronze finish provides a specific visual tone that aligns with bronze-colored hardware layouts and helps keep exposed portions of this semi-concealed hinge consistent with surrounding trim. As a semi-concealed hinge, it positions most of the working parts out of direct sight while still remaining accessible for installation and adjustment tasks.
The screw-on design of this Sugatsune CH-75/GB center hinge allows it to be secured using typical screw-driving steps, which fits straightforward installation sequences on wood-based doors and frames. The hinge is identified as a semi-concealed face-frame style, so it works with layouts where part of the hinge is visible and part is set back against the frame, helping balance appearance with access for mounting. Its 2-15/16 inch center-hinge sizing supports positioning in the middle of folding door runs as described, so the door pair can articulate around that point. With the hinge snapping at open and closed positions, installers can align doors to those end positions during setup, then tighten fasteners while the hinge holds each leaf at a repeatable angle. The bronze finish contributes a consistent visual reference line along the exposed knuckles, which can be used to judge straightness when sighting down a row of hinges.
This Sugatsune America CH-75/GB hinge is identified as a center hinge for folding doors, so it is used at the joint where door panels meet and rotate together. As part of the semi-concealed hinge class, it suits face-frame-based installations where some hardware is visible at the frame edge while the rest sits into the opening. The 2-15/16 inch center-hinge description defines its general scale, aligning it with door sections sized to that hinge length. Its 180 degree opening capability supports applications where the connected folding doors need to clear the access area by rotating fully back. Installers can integrate this hinge with other hinges in a folding system so that the center connection follows the same swing arc as outer hinges. The bronze finish allows the visible parts of this center hinge to coordinate with bronze-toned door pulls or other bronze hinge elements on the same assembly.
The 180 degree screw-on center hinge design gives a full swing range, so doors can be mounted to open flat in line with adjacent surfaces when the layout calls for maximum clear opening. Its snap-in behavior at both fully open and fully closed positions holds the door panels in those positions, which can simplify alignment of reveals during installation and support repeatable positioning during daily use. The four-hole configuration allows fasteners to be placed in a stable pattern that resists twisting, helping the center joint stay true as folding doors cycle. With three knuckles forming the pivot, the hinge provides a defined rotation center that can be matched across multiple center hinges in a run, supporting smoother, synchronized motion. As a semi-concealed face-frame hinge from Sugatsune America, it is intended for installations where the working mechanism is partly hidden yet accessible, which aids ongoing adjustments or door removal tasks that rely on clear access to the hinge body.
The Sugatsune CH-75/GB is described as a center hinge for folding doors, so it serves as the pivot point between door panels in a folding door setup.
The hinge is specified for 180 degree opening, allowing connected folding doors to swing fully open for wide access and to lay back along adjoining surfaces when configured that way.
This center hinge snaps in at open and closed positions, providing distinct detents that help keep folding doors positioned during everyday use and during alignment work.
The CH-75/GB is a screw-on hinge, so it mounts by driving screws through its four mounting holes into the door and frame surfaces during installation.
The hinge is described with four holes and three knuckles, providing multiple fastening points and a defined three-part pivot that support stable, repeatable folding movement.
The SAP description notes a bronze center hinge for folding doors at 2-15/16 inch, so it combines a bronze finish with a defined hinge length for fitting similar-scale doors.
The Sugatsune CH-75/GB semi-concealed center hinge provides 180 degree opening, so folding doors can clear the access area when rotated fully back. Its snap-in action at open and closed positions supports stable door behavior in both everyday operation and setup stages. The four-hole, three-knuckle layout gives a defined mounting and pivot structure that suits repeatable folding motion across multiple doors. With a bronze finish and 2-15/16 inch center-hinge sizing, it aligns with bronze-focused hardware schemes and door sections built around that scale. For folding door projects that rely on a center pivot hinge with these characteristics, this CH-75/GB hinge from Sugatsune America offers a focused solution built around folding applications.
