Sugatsune bi folding hinge is a center hinge from the HG-JC70 Series designed for folding doors, so it supports bi-fold layouts where a controlled closing action is important. The hinge integrates a self-closing and damping function, which pulls the folding door shut and slows it at the end of travel, so the panels do not slam. This self-closing and damping action gently and reliably closes folding doors, which matters on finished cabinetry and built-ins where edge damage and noise must be kept down. The hinge is designed for 1 inch door thickness, so it fits door constructions built around that dimension. A black finish provides a dark, uniform appearance, which fits projects that call for black builders hardware in visible locations on folding doors.
This soft close bi folding hinge uses an adjustable damping mechanism, so the soft-closing speed can be adjusted with a hex key once the doors are hung. That adjustment lets you respond to how a 1 inch thick door behaves at different heights up to the maximum door size of 17-3/4 inches wide by 106-5/16 inches high. By staying within the 33 lbs door weight capacity when using 3 hinges, the self-closing and damping function operates as intended across the travel. The black finish stays part of the final visible installation, matching other dark builders hardware around the opening.
The Sugatsune HG-JC70 Series 1 inch door thickness bi folding hinge with soft-close is specified for doors built to that 1 inch thickness, which helps cabinetmakers and installers standardize rail and stile construction. With a maximum door size of 17-3/4 inches wide by 106-5/16 inches high, the hinge supports narrow, tall folding panels used on closets, utility cabinets, and similar openings within that range. The center hinge format places the self-closing and damping function between the folding panels, so the folding action is controlled at the joint where the two leaves meet. Being part of bi-fold door hardware, this setup lets the two panels work together as a single folding assembly.
The integrated self-closing and damping function gently and reliably closes folding doors, which creates a controlled motion that stays consistent day after day. Quiet folding door operation means the doors close without slamming, while the self-closing function also prevents the door from springing back, so panels stay seated against the cabinet or framing. When the soft-closing speed is adjusted with a hex key, the installer can match the damping to the actual panel height up to 106-5/16 inches and the door weight supported by 3 hinges at 33 lbs. This tuning helps reduce bounce at closing, which protects finished edges along the 1 inch thick doors and keeps the black bi fold door hardware working smoothly in regular use.
The Sugatsune HG-JC70 Series bi folding hinge is designed for 1 inch door thickness, so it suits folding panels built around that thickness in cabinetry or similar installations.
The hinge supports a maximum door size of 17-3/4 inches wide by 106-5/16 inches high, guiding how tall and wide each folding panel can be laid out in a project.
The door weight capacity with 3 hinges is 33 lbs, so designing panels within that weight range supports consistent self-closing and damping performance.
The soft-closing speed on the HG-JC70-BL hinge can be adjusted with a hex key, allowing on-site tuning of the door closing speed to match panel size and weight.
The center hinge integrates a self-closing and damping function that pulls folding doors shut and slows them at the end of travel, reducing noise and impact at closing.
The HG-JC70-BL hinge provides quiet folding door operation by combining soft-close damping and self-closing action, so the doors close quietly without slamming or springing back.
The HG-JC70-BL from Sugatsune America pairs 1 inch door thickness support with bi-fold door hardware performance, so folding doors operate smoothly in daily use. With adjustable soft-closing speed by hex key, a maximum door size of 17-3/4 inches wide by 106-5/16 inches high, and a 33 lbs door weight capacity using 3 hinges, this black center hinge creates quiet folding door operation on projects that value controlled, reliable closing.
