Sugatsune inset pocket door kit is a pocket door hardware system designed for inset cabinet doors, so the door can slide back into the cabinet when open instead of swinging into the workspace. The system is specified for cabinet depths of 19-1/2 inches, so it targets cabinets built around that depth for predictable door travel. It supports door heights from 47-1/4 inches to 63 inches, so it suits medium-height doors often used in multimedia, workspace, or storage cabinets. The kit is part of the ST20 M-Type series, identified as ALT-ST20-D360M-19, so it aligns with projects that call out that specific Sugatsune America hardware line. As pocket door hardware in the multimedia and workspace components category, it addresses applications where doors must clear equipment fronts while remaining accessible.
This inset pocket door system is specified for a minimum cabinet depth of 19-1/2 inches, so cabinet interiors must be laid out around that depth to accommodate the pocket travel path. Door height compatibility from 47-1/4 inches to 63 inches defines the vertical working range, so case openings can be planned to keep the door fully supported by the 3 slides. As a pocket door slide system in the shelf, closet, and garage organization category, it focuses on doors that retreat into the cabinet footprint instead of projecting into aisles or work zones. The ST20 M-Type designation provides a clear reference to this Sugatsune America configuration, which helps align door sizing and casework dimensions to the specified operating range.
This inset pocket door system is positioned in the multimedia and workspace components group, so it fits cabinets where doors need to move cleanly out of the way in front of screens, equipment, or work surfaces. The pocket door hardware belongs to the pocket door slides class, so its primary role is providing guided sliding movement that shifts the door into the cabinet body. Using 3 slides to carry the door allows the mechanism to support the full specified height range of 47-1/4 inches to 63 inches, so taller doors within that band can still retract smoothly. The synchronized board works with these slides to coordinate motion across the door width, so the leading edge does not skew during travel. With 3 hinges and 3 hinge mounting plates in the system design, the door can pivot from closed position to pocket position while staying aligned with the slide track, keeping the motion path consistent along the door edge.
The 5-speed adjustable soft-closing dampers are central to how this pocket door hardware controls closing behavior, because the damper setting can be tuned so doors within the rated height range settle into position without harsh impact. The single damper specified in the kit works with the synchronized board and 3 slides, so damping is applied as part of the coordinated movement rather than acting on a loose, unsupported panel. The minimum cabinet depth of 19-1/2 inches ties directly to this motion, because adequate depth lets the door fully retract while the soft-closing function completes its travel. As a pocket door hardware assembly in the ST20 M-Type line, identified by part number ALT-ST20-D360M-19, it offers a defined combination of slides, hinges, mounting plates, synchronized board, and damper, so project documents can reference a single configuration when calling out the door system.
The Sugatsune inset pocket door kit is specified for a minimum cabinet depth of 19-1/2 inches, which provides the space needed for the door to retract fully into the cabinet body.
The pocket door hardware is rated for door heights from 47-1/4 inches to 63 inches, so it suits medium-height cabinet doors typically used in multimedia and workspace cabinetry.
The 5-speed adjustable soft-closing dampers let installers set one of five closing speeds, so the door can slow smoothly at the end of travel and reduce hard closing against the cabinet.
The synchronized board coordinates the 3 slides, so both sides of the door move together as it opens and retracts, which helps keep the door tracking square within the cabinet opening.
The system uses 3 slides to support the specified door height range, distributing guidance along the door edge so the panel travels more evenly when moving into and out of the cabinet.
ALT-ST20-D360M-19 identifies this specific Sugatsune ST20 M-Type inset pocket door system, tying together the slides, hinges, mounting plates, synchronized board, and soft-closing damper.
The Sugatsune inset pocket door kit specified as ALT-ST20-D360M-19 provides a defined pocket door hardware solution for cabinets with a minimum depth of 19-1/2 inches and door heights between 47-1/4 inches and 63 inches. Its 3-slide layout, synchronized board, 3 hinges, 3 hinge mounting plates, and 5-speed adjustable soft-closing damper are all configured around that application range, so project drawings can call out one system for both movement and closing control. For multimedia, workspace, and organization cabinetry that needs inset doors to retract cleanly into the cabinet, this pocket door slide system offers a coordinated Sugatsune America hardware configuration ready to integrate into casework planning.
