RealCraft Box Rail Exterior Sliding Barn Door Hardware sets the industry standard, starting with better raw materials and offering more flexibility for the install process...but the secret is in the trolley! The craftsmanship that goes into our trolleys is unmatched, featuring years of smooth operation and dependability.
Heavy-Duty Industrial Box Rail (Single Track) is intended for heavy-duty doors. Similar in design to the Standard Duty Box Rail, this hardware is available in a 600 lb weight limit. The trolleys come with an adjustable apron that clasps the top of the door (powder coated, if applicable). Great for both exterior or interior doors.
CHOOSING A KIT LENGTH:
Single Door: Multiply your single door width by two for optimum track length. For a 3ft door, you would typically need a 6ft rail kit.
Double Doors: For biparting doors, choose a kit length for the total track length needed, then change "Quantity of doors on track" to 2 to add hardware for an additional door.
APRON MIN/MAX DOOR THICKNESS*
*Can accommodate thicker doors by mortising apron into door
CHOOSING A MOUNTING STYLE:
Wall Mounted: For wall-mounted single doors, double the width of the door to determine the rail length you will need. For example, if you have a 3'W door, you will need a minimum of 6' of track. For help determining the amount of track you will need for your application, please call us.
Soffit (ceiling) Mounted: For doors that are soffit mounted within the opening, measure the opening width. Choose the rail size that is larger than the opening (see the "Actual Rail Lengths" chart below)--the rail can be cut onsite to exactly fit the opening size.
Biparting, or Multi-door:
Wall Mounted: For biparting doors that are wall mounted, choose a kit length for the total track length needed, then change "Quantity of doors on track" to 2 to add hardware for an additional door. For help determining the amount of track you will need for your application, please call us.

All RealCraft barn door hardware kits are machined in Washington State, USA.
Our color hardware finishes are powder-coated steel. Unfinished raw steel is just that - the metal is not treated, and it's intended to have a worn and weathered look over time. The material is susceptible to pitting and rust, giving the hardware a time-worn look that meshes well with rustic, shabby chic, and industrial design schemes.
This hardware ships free within the continental United States. Free shipping excludes expedited shipping, international shipments, and oversize orders that require LTL shipping. Fast lead time: In-stock items ship in 1-3 days! Most orders ship same day if ordered by 12 PM Pacific time.
600 lb kits over 16' must go through a freight carrier, and cannot be expedited. *Free standard shipping within the contiguous United States.

The brokerage fees and Canadian taxes are charged at the door by the shipping carrier (FedEx) when the shipment is delivered.
