Sugatsune inset pocket door kit provides an inset pocket door system designed for cabinet applications that need doors to retract out of the way. The kit is built around 4 slides that guide the door smoothly, helping the door travel on a defined path so it tucks cleanly inside the cabinet opening. A synchronized board coordinates movement across the slides, so the door tracks evenly rather than racking under load. The system uses 3 hinges with 3 hinge mounting plates to connect the door to the slide mechanism, giving a stable pivot point so the door can swing out and then slide back in. With a minimum cabinet depth of 22-1/2 inches and a door height range of 47-1/4 to 63 inches, the kit targets mid-size cabinet doors where full retraction is important for workspace access.
This inset pocket door system is designed around a 22-1/2 inch minimum cabinet depth, so the hardware geometry assumes that depth when the door retracts. That depth allocation lets the door store fully inside the cabinet line, which is important when the front needs to clear adjacent equipment or work surfaces. The door height specification of 47-1/4 to 63 inches defines a working range where the slide length, hinge positions, and synchronized motion are tuned to the panel size. Within that range, the four slides and synchronized board coordinate movement so the panel remains aligned through the travel. The use of dedicated hinge mounting plates sets consistent hinge locations relative to the slides, which supports repeatable alignment across cabinets built to the same depth and door height parameters.
This Sugatsune America inset pocket door kit is part of pocket door hardware for multimedia and workspace components. That positioning suits cabinets where doors need to move completely out of the working envelope so screens, tools, or equipment fronts remain accessible. The minimum cabinet depth of 22-1/2 inches matches deeper cabinet bodies that often house electronics or workspace storage, so the pocket can accept the full door thickness and swing path. Door heights from 47-1/4 to 63 inches align with upper cabinets, tall storage bays, or workstation enclosures where a single vertical door covers the opening. The further door retraction capability compared with the ALTST20-D360 series helps the door clear the cabinet front more deeply, which matters when adjacent components or users operate close to the cabinet face.
The inset pocket door system integrates 5-speed adjustable soft-closing dampers, giving the installer control over the closing behavior so the door can be tuned to the door weight and usage pattern. That adjustability lets the motion slow in a controlled way at the end of travel, which reduces impact at the stop and supports quieter operation in work areas. The further door retraction design than the ALTST20-D360 series allows the door to sit deeper inside the cabinet, which minimizes projection into the opening and supports cleaner access to the interior. Coordinated by the synchronized board, the four slides share the load and timing, so retraction and extension stay even across the door height. The three hinges and hinge mounting plates anchor the door to that motion path, helping the panel swing and slide along a defined arc that can be repeated across multiple cabinet builds using the same ALT-ST15-D360LL-22 pocket door configuration.
The Sugatsune inset pocket door kit is specified for a minimum cabinet depth of 22-1/2 inches, which sets the case depth needed for the door to retract fully into the cabinet.
The inset pocket door system is designed for doors from 47-1/4 to 63 inches high, so the slide travel and hinge layout are matched to medium-tall cabinet doors in that range.
The 5-speed adjustable soft-closing dampers let the closing motion be tuned, so the door decelerates smoothly at the end of travel and reduces impact when it seats.
The further door retraction allows the door to sit deeper inside the cabinet than the ALTST20-D360 series, which keeps the opening clearer for access to interior components.
The system uses four slides so the door load is distributed across multiple tracks, which supports stable guidance of the door during opening and retraction.
The synchronized board coordinates movement between the slides, helping the door travel evenly so the panel stays aligned at the cabinet face and inside the pocket.
This inset pocket door kit from Sugatsune America combines pocket door slides, hinges, mounting plates, a synchronized board, and 5-speed adjustable soft-closing dampers into a coordinated pocket door hardware solution. The specified minimum cabinet depth of 22-1/2 inches and the door height range of 47-1/4 to 63 inches define the cabinet formats where this system is intended to work, giving clear design parameters during layout. The further door retraction than the ALTST20-D360 series supports applications where deeper clearance inside the cabinet opening is important.
