Omega National ST Series tambour hardware is a frameless mount spring tension track system that manages vertical motion for tambour doors in kitchen and bath cabinets. The hardware pack is designed for appliance garages and tambour doors where controlled, smooth travel is important during daily use. The system is specified for tambour doors up to 36 inches wide, so one kit can serve a range of cabinet widths on the same project. It is rated for doors up to 19 inches high and 0.220 inches thick, which defines the cabinet opening and door construction this system is built to handle. By grouping the tension spring, wood dowel, donuts, and plastic guide rails into a matched system, the track keeps the door aligned as it moves. That alignment helps the door glide cleanly in its path and supports repeatable motion over the life of the cabinet.
The spring tension track system is built for frameless mounting, so it aligns directly to cabinet end panels without a face frame in the way. That matters when laying out appliance garages in European-style cases or other frameless constructions. The approximate cabinet opening height for this system is 16-1/2 inches, based on a guiderail height of 18 inches, which defines the vertical space where the door operates. By working within that opening height, the door stays engaged in the plastic guide rails for the full travel path. The ability to recess or flush mount to the end panels offers a choice in how prominently the track shows inside the cabinet. Installers can set the guiderails relative to shelves or counter surfaces while still respecting the defined opening and door size range.
This frameless mount spring tension track system is used in appliance garages and tambour door cabinets where a vertical, roll-up style door needs guided movement. The hardware is part of the Appliance Garages & Tambour Doors product class, so it is intended for kitchen and bath cabinet applications rather than general sliding doors. By controlling tambour doors up to 36 inches wide, the system covers common upper cabinet widths and appliance garage spans found in residential kitchens. The 19 inch maximum door height aligns with compact garage-style openings that sit on countertops or within wall cabinets. With an approximate cabinet opening height of 16-1/2 inches and guiderail height of 18 inches, the track sets the working envelope for the door inside the case. This defined geometry helps the door stay engaged with the plastic guide rails during both opening and closing.
The spring tension element in the track system works with the tambour to manage movement from top to bottom, so the door is easily controlled during operation instead of dropping or binding. That control matters wherever appliance garages open and close frequently throughout the day. The plastic guide rails provide a dedicated path that keeps the door aligned along both sides, supporting smooth gliding that reduces resistance and helps protect the door edges. Trim-to-fit wood dowels allow the horizontal support components to match narrower cabinet widths, so the same ST-2-24-AL system can adapt to different openings while maintaining the intended geometry. Because the system is designed for frameless mounting, its layout is consistent across frameless casework, which supports repeatable installation methods from cabinet to cabinet. The ability to choose recessed or flush mounting to end panels offers control over the track position, which can help coordinate clearances with adjacent doors, countertops, or interior storage. Within its specified 0.220 inch door thickness capacity, the system is tuned to work with a defined tambour construction, supporting reliable engagement with the guide rails over ongoing use.
The ST-2-24-AL system is for appliance garages and tambour doors in kitchen and bath cabinets, so it fits projects using roll-up style doors in those cabinet categories.
The spring tension track system controls tambour doors up to 36 inches wide, allowing it to serve standard and wider cabinet openings within that range.
The hardware is specified for tambour doors up to 19 inches high and 0.220 inches thick, defining the door size and construction it is designed to handle.
Frameless mounting means the track aligns to cabinet end panels without a face frame, which suits European-style casework and similar frameless cabinet constructions.
The approximate cabinet opening height is 16-1/2 inches, based on an 18 inch guiderail height, so the door travels within that defined vertical space.
The system can be recessed or flush mounted to end panels, giving flexibility in how the guiderails sit relative to cabinet interiors and visible edges.
The Omega National ST Series tambour hardware pack ST-2-24-AL offers a frameless mount spring tension track system matched to tambour doors in appliance garages and similar cabinets. With defined limits for door width, height, and thickness, it gives clear parameters for door construction and cabinet layout. The trim-to-fit wood dowels, plastic guide rails, and option for recessed or flush mounting to end panels support a controlled door path that glides smoothly from top to bottom. For projects that use tambour doors within the specified 36 inch width and 19 inch height range, this system provides a coordinated track solution centered on consistent door movement.
