Sugatsune inset pocket door kit is a pocket door hardware system designed for inset cabinet doors that slide back into the cabinet. The kit is classified as pocket door hardware and uses four slides, which guide the door smoothly as it moves in and out of the cabinet opening. The inset pocket door system uses fittings that allow the door to retract further into the cabinet than the ALTST20-D360 series, which provides more clearance in front of the cabinet face when the door is open. The system is specified for a minimum cabinet depth of 24-1/2 inches, so it is aimed at deeper cabinet applications where a retracting door is needed. It supports door heights from 47-1/4 inches to 63 inches, which targets mid-height doors commonly used in multimedia or workspace cabinetry, helping the door travel correctly within that size range.
This inset pocket door system is specified for a minimum cabinet depth of 24-1/2 inches, so the cabinet layout needs that depth to allow the door and four slides to travel behind the front opening. The defined door height range of 47-1/4 inches to 63 inches means the linkage, slides, and synchronized board are configured to support doors within that vertical span, helping keep the door square during retraction. Because the fittings allow the door to retract further into the cabinet than the ALTST20-D360 series, the door sits deeper inside the cabinet when open, which affects how far adjacent components can project past the face of the cabinet without interfering with the door.
The inset pocket door system is listed under Shelf, Closet & Garage Organization and Multimedia and Workspace Components, so it is oriented toward cabinets in those environments where doors must clear the front workspace. The minimum cabinet depth of 24-1/2 inches suits deeper cabinets commonly used for multimedia equipment or workspace storage, where there is room to house a retracting door. The specified door height range of 47-1/4 inches to 63 inches aligns with mid-height doors on tall base cabinets or upper storage units in these applications. Fittings that allow the door to retract further into the cabinet than the ALTST20-D360 series let the door sit deeper inside the case, which supports layouts where equipment, work surfaces, or adjacent doors extend beyond the cabinet front.
The pocket door kit uses four slides, which share the door load across multiple tracks so the motion remains guided and helps the door stay aligned through full extension and retraction. The system uses a synchronized board, which coordinates the slide motion so both sides of the door move together, helping reduce racking as the door travels. The 5-speed adjustable soft-closing dampers manage the last part of the stroke, slowing the door at closing and allowing speed adjustment to match the door weight and preferred feel. Hinges and hinge mounting plates in the system establish the pivot relationship between the door and the slides, which is central to how the door moves from the closed position to the pocket position while staying flush when shut. The manufacturer part number ALT-ST15-D360LL-24 identifies this specific configuration, which matters when matching future hardware orders to existing cabinet runs or coordinating with design documentation.
The Sugatsune inset pocket door kit is designed for inset doors, so the door sits flush within the cabinet opening when closed and then retracts into the cabinet on the pocket door slides.
This inset pocket door system specifies a minimum cabinet depth of 24-1/2 inches, which provides the space needed behind the front opening for the door and four slides to retract fully.
The ALT-ST15-D360LL-24 pocket door hardware is specified for door heights from 47-1/4 inches to 63 inches, aligning the slide geometry and synchronized board to support doors within that size range.
The 5-speed adjustable soft-closing dampers slow the door at the end of travel, and their adjustment lets the closing rate be tuned to the door weight and preferred operational feel.
This inset pocket door system uses fittings that allow the door to retract further into the cabinet than the ALTST20-D360 series, providing greater clearance in front of the cabinet when the door is open.
The synchronized board in this pocket door kit coordinates the motion of the slides, helping both sides of the door travel together for smoother, more controlled operation.
The Sugatsune inset pocket door kit with part number ALT-ST15-D360LL-24 combines four slides, a synchronized board, and 5-speed adjustable soft-closing dampers to support inset doors in deeper cabinets. The minimum 24-1/2 inch cabinet depth specification and 47-1/4 inch to 63 inch door height range define where this pocket door hardware fits best in multimedia and workspace cabinetry. Fittings that allow further door retraction than the ALTST20-D360 series help keep the door clear of the work area when open, so this system suits projects that rely on clean, unobstructed cabinet fronts.
