Sugatsune overlay pocket door kit is a pocket door hardware system designed for overlay cabinet doors using four slides and an overlay damper unit. The system is part of the ST15 LL-type series with manufacturer part ALT-ST15-D10LL-16, so it targets a specific application where buyers need matched components. Minimum cabinet depth is 16-9/16 inches, which sets the cabinet interior dimension needed to run the slide travel correctly. The kit suits door heights from 47-1/4 inches to 63 inches, covering a range of medium to tall doors in one system for consistent planning across similar cabinets. The overlay pocket door system offers door alignment adjustability, allowing fine tuning of door position after mounting to obtain straight reveals. Fittings allow the door to retract further into the cabinet than the ALTST20-D10 series, giving the door a deeper parking position that clears the opening better.
The minimum cabinet depth of 16-9/16 inches defines the carcass size needed so the four slides and synchronized board can travel fully without interference. Door height suitability from 47-1/4 inches to 63 inches aligns the slide length and geometry to that door range, which supports predictable movement on cabinets built to those dimensions. The overlay amount up to 3/8 inch (10 mm) describes how far the door projects past the cabinet front when closed, guiding face frame or panel layout so the overlay pocket door kit works correctly. Door alignment adjustability in the system provides the ability to shift the mounted door positions, giving the installer a way to correct minor cabinet or hinge placement variation.
This overlay pocket door system is categorized as pocket door slides within pocket door hardware, so it is aimed at cabinet applications where doors need to slide back into the cabinet. The minimum cabinet depth of 16-9/16 inches focuses it on cabinets deep enough to house a full-height door on four slides. Door height coverage from 47-1/4 inches to 63 inches places it in a size range often used for taller upper cabinets, multimedia units, or workspace enclosures, allowing one hardware specification across those builds. The overlay amount up to 3/8 inch (10 mm) positions the system for overlay-style fronts rather than flush inset, which shapes how cabinet faces and adjacent fronts are designed around it.
The presence of four slides in the pocket door slides kit distributes support along the door travel, which helps the door track predictably when moving between closed and retracted positions. The synchronized board ties movement between components so the door motion stays coordinated, helping the door maintain alignment while traveling. Door alignment adjustability within the overlay pocket door system allows final tweaking of door position relative to the cabinet front, which reduces rework when cabinet construction tolerances vary slightly. The overlay damper unit with adjustment screw lets the installer tune the damping response to the specific door, helping achieve a controlled, quieter close that suits the door size. Fittings that pull the door further into the cabinet than the ALTST20-D10 series shift the rest position deeper into the cabinet, improving front clearance for working in the opening.
The Sugatsune overlay pocket door kit requires a minimum cabinet depth of 16-9/16 inches, which sets the interior space needed for full slide and door retraction travel.
The overlay pocket door system supports door heights from 47-1/4 inches to 63 inches, matching the slide design to that door size range for proper motion.
The pocket door hardware allows an overlay amount up to 3/8 inch, or 10 mm, which defines how far the door overlaps the cabinet front when closed.
The overlay damper unit uses an adjustment screw to tune damping, so the door closing action can be adjusted to better match the installed door behavior.
This overlay pocket door system uses fittings that retract the door further into the cabinet than the ALTST20-D10 series, increasing clearance at the front opening.
The kit offers an overlay amount up to 3/8 inch and door alignment adjustability, so the door can overlay the front while still being fine-tuned to align with adjacent fronts.
This overlay pocket door hardware from Sugatsune America brings together four slides, a synchronized board, an overlay damper unit with adjustment screw, and fittings that retract the door further into the cabinet than the ALTST20-D10 series. The specified minimum cabinet depth of 16-9/16 inches and door height range from 47-1/4 inches to 63 inches define where it fits best in cabinet projects. When those dimensions and overlay up to 3/8 inch align with your cabinet design, this pocket door slides kit offers a matched set of components built for that configuration.
