Topline Grant Single Track XHD is an aluminium sliding door track designed to carry a sliding door along a guided path, so doors move smoothly along the opening. The 16ft length provides a continuous run for long openings or multiple-door layouts, which helps avoid joints that can interrupt door travel. The track is made from aluminium, giving a rigid but workable base for mounting in typical builders hardware applications. The anodised finish protects the aluminium surface during normal use, which helps the track resist surface wear where hangers run. As part of the sliding door hardware range, this single track forms the structural guide for door hangers, keeping doors aligned as they open and close. The Topline Grant designation identifies it within Hettich America Corporation systems, which helps match the track to the correct sliding door hardware family when planning a job.
The track has drill holes already provided for ease of attachment, so installers can set the line of the track and secure it directly through these openings. The web description notes screws not included, recommended 4.8 x 32 mm oval head screws, which points to a screw size and head style suited to the track holes. Using screws matching the 4.8 mm by 32 mm recommendation helps the fastener fill the hole and bite into the mounting structure, supporting the load of sliding doors along the full 16ft run. Because the component is a single track, the mounting line also sets the final door alignment along the opening, so careful placement of fasteners through the provided drill holes helps keep doors running straight.
This Hettich America Corporation Topline Grant Single Track XHD belongs to the sliding door hardware class, so it suits projects needing a guided track for sliding door panels. The 16ft length makes it practical for wide wall openings, long closets, or multi-panel runs where a continuous track is preferred. The aluminium, anodised body keeps overall weight manageable while still forming a strong guide, which is useful when mounting to typical timber or structural framing in builders hardware applications. Because the drill holes are already provided for ease of attachment, the track also supports repeatable layout on jobs with similar spans, letting installers align several openings using the same hole pattern. In woodworking-focused environments, the track integrates into broader builders hardware setups where a defined sliding path is required.
The anodised aluminium running surface of this single track XHD provides a smooth interface for hangers, which helps the sliding door hardware operate with less friction along the 16ft span. The extra heavy-duty XHD designation within the Topline Grant line signals that the track is intended to carry higher loads than lighter-duty tracks, supporting heavier doors in service. The pre-formed drill holes guide screw positioning along the entire rail, which distributes the load across multiple points so the track resists sagging between supports. The recommended 4.8 x 32 mm oval head screws match the drill hole sizing, which allows the screw head to seat correctly against the track and grip the substrate. This combination of material, finish, length, and mounting details works together so the track maintains alignment under everyday sliding door use.
Topline Grant Single Track XHD is an aluminium sliding door track, so it serves as the guided rail that sliding door hardware uses to move door panels along an opening.
The track length is 16ft, which allows one continuous run over wide openings or multi-panel layouts without cutting and joining multiple shorter tracks.
The anodised finish protects the aluminium surface, which helps the running face resist wear as door hangers roll along the track during normal sliding operation.
The track has drill holes already provided for ease of attachment, so it is fastened through these holes into the supporting structure along the desired mounting line.
The web description specifies recommended 4.8 x 32 mm oval head screws, which matches the drill hole sizing and supports secure attachment during installation.
The XHD term identifies the track as extra heavy-duty within the sliding door hardware range, which relates to using it in more demanding sliding door applications.
Choose the Topline Grant Single Track XHD when a 16ft aluminium, anodised sliding door track fits the opening span and duty rating needed on a project. The drill holes already provided for ease of attachment streamline layout for installers who want predictable mounting points. Using the recommended 4.8 x 32 mm oval head screws aligns fastener size with the track design, which supports secure fixation along the full length. For jobs built around Hettich America Corporation sliding door hardware, this single track XHD provides the guiding rail that ties the system together and helps doors travel consistently.
