Description
The 14 Ft Top Mount Box Rail with Flashing Bracket from HILLMAN is a heavy-duty barn door rail designed for smooth top-mounted sliding operation, ideal when you want dependable performance and a clean, functional look. At 14 feet in length and rated to carry up to 450 lbs., this rail handles large interior or exterior sliding doors, offering the capacity needed for oversized or solid-core doors used in garages, workshops, barns, or loft-style interiors. Its top-mount configuration keeps the track unobtrusive while providing stable support for frequent use, and the included flashing bracket helps integrate the rail with door openings where added coverage is desired. Use it to retrofit an existing opening or to create a wide sliding doorway that saves space and adds rustic or industrial character to a room.
