Heavy Duty Flat Track Exterior Barn Door Hardware (800lb)


Industrial Flat Track Exterior Sliding Barn Door Hardware is intended for heavy-duty doors weighing up to 800 lbs. While similar in design to Classic Flat Track, Industrial hangers are available in either an offset or straight design, depending on door thickness.

Available in unfinished steel or a variety of powder-coated finishes including black and oil-rubbed bronze, our heavy-duty barn sliding door hardware is ideal for interior or exterior projects.

Lag Bolts Not Included: Recommend The Use If 3/4" Lag, 2.5" length

For doors that are 2-1/4" thick to 2-3/4" thick, choose the Offset Hanger. For doors that are 3" to 3-1/2" thick, choose the Straight Hanger.

Industrial Flat Track lead time:  8' - 20' kits in Raw Steel ship in 1-3 business days. Powder-coated finishes up to 20' ship in 2 weeks. Sizes above 20' are made to order, and ship in 3-4 weeks. *Free standard shipping within the contiguous United States. 


This product consists of heavy-duty sliding door tracks and rollers that are made to order. This product is not returnable.


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.


If you're adding a Soft Stop to your flat track hardware, keep in mind that it's recommended for interior use only. Soft stops can be used with flat tracks 5' and longer. If using two soft stops (one at each end of the track), this configuration is compatible with one-piece tracks over 12 feet in length, or with 2-piece tracks 10 feet in length and longer. Even if the overall weight rating for your hardware kit is higher, the weight rating for a Soft Stop is 220 lbs.


Doors are not included with the purchase of hardware.


If you have questions, or if your project requires special consideration, please call 1-800-694-5977. We'd be happy to help!


For a single door, multiply your door width by two to get optimum track length. Example: For a 3' wide barn door, you'd need a 6' barn door hardware kit.

For bi-parting doors, you'll need to add the widths together and then multiply that sum by two. Example: For two 3' wide bi-parting doors, you'll need a 12' track. When you are making your selections in the menu, change the quantity of doors on track to the correct amount so we can send you all the hangers and extra hardware you'll need.

If your door requires a track length that falls between sizes, you can round up to the next size and pair with the adjustable end stop. This will allow you to choose where the door stops on the track. We are also able to cut tracks to your specifications.


For custom track lengths, call us at 1-800-694-5977
