XHD Standard Set of Fittings is a Hettich America Corporation sliding door hardware solution designed for a 1-door application, so a single sliding panel can be planned as a complete assembly. This set belongs to the sliding door hardware class, so it is intended for guided horizontal movement rather than swinging action on hinges. The components are configured for an XHD application, which defines how the parts work together as one running system. Because it is supplied as a standard set for one door, layout decisions can be based on a consistent group of parts rather than mixing components from different systems. The product is identified by manufacturer part 9191126, which ties specifications back to Hettich documentation for repeat ordering and project standardization.
The two runner carriages with precision ball bearing rollers carry the moving load of the door, so mounting focuses on aligning these carriages with the running surface to create a straight, low-friction path. Height adjustable retaining pins built into the runner carriages allow the door height to be shifted after mounting, which supports fine-tuning the top and bottom gaps to suit surrounding panels or floors. The two door fixing plates connect the door to the running components, so their position on the door determines how the panel hangs and tracks along the hardware line. The base glider works in conjunction with the upper running gear, guiding the lower edge so the door does not wander out of plane during travel. End stops are positioned at the limits of travel, so the carriages contact them at consistent points, setting repeatable open and closed positions.
This XHD Standard Set of Fittings from Hettich America Corporation is part of the sliding door hardware category, so it is intended wherever a single sliding door leaf is required rather than a pair of coordinated doors. Because the set contains all components for a 1-door application, it suits layouts where one moving panel needs a complete track and guidance solution dedicated to that leaf. The two runner carriages act as the primary running elements, so they are placed along the upper structure that will bear the door load while allowing the precision ball bearing rollers to travel freely. The base glider is positioned to guide the lower portion of the door, so it works with the upper carriages to keep the panel aligned through the full stroke between the two end stops.
The pairing of runner carriages with precision ball bearing rollers is central to this set, because the rollers reduce friction along the running path, which supports smooth, predictable motion during repeated sliding cycles. Height adjustable retaining pins give an adjustment function within the carriages, so the vertical position of the door can be altered without remaking primary mounting points, which helps correct for small dimensional shifts in surrounding construction. The two door fixing plates define where the running hardware connects to the door, so placing them symmetrically helps distribute the load into the panel and supports straight tracking. End stops at each end of the run give fixed impact points for the carriages, so the open and closed positions are defined by the hardware rather than by incidental contact with surrounding construction. The base glider supplements these functions by supporting the lower edge of the door, so side sway is limited and the running gear can focus on carrying the vertical load. The set structure under a single manufacturer part number, 9191126, ties all these elements into one coordinated system, which simplifies specifying the same configuration across multiple openings.
The XHD Standard Set of Fittings provides a coordinated Hettich sliding door hardware solution for a 1-door application, so one moving panel has matching running gear, guidance, and travel-limiting components.
The runner carriages with precision ball bearing rollers support and guide the sliding door along its track, reducing friction so the door moves smoothly along the running path.
The height adjustable retaining pins allow the mounted door to be shifted vertically on the runner carriages, which helps set the reveal and bottom clearance relative to nearby surfaces.
The door fixing plates connect the sliding door panel to the running hardware, defining attachment points that determine how the door hangs and tracks along the sliding system.
End stops define the limits of carriage travel, so the sliding door stops at fixed open and closed positions rather than overrunning the track or adjacent construction.
The base glider supports the lower edge of the sliding door, helping maintain alignment so the panel tracks straight while the upper runner carriages carry the vertical load.
The XHD Standard Set of Fittings from Hettich America Corporation combines runner carriages with precision ball bearing rollers, height adjustable retaining pins, door fixing plates, end stops, a base glider, and fixing material in one coordinated system for a 1-door application. Using this set as the basis for a sliding opening standardizes how the door is supported, guided, and limited at each end of travel. For projects supplied through Wurth Baer Supply, selecting this specific set by manufacturer part 9191126 ties your sliding door hardware choice to a defined configuration suited to a single moving panel.
