Stainless Steel Box Rail Barn Door Hardware Interior & Exterior (400 lb)

RealCraft 400 lb. Stainless Steel box rail interior & exterior 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.

More Info

Lag bolts are used to attach the track to the wall. Choose our lag bolts for a matching stainless steel finish.


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.


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


For bypassing doors, you’ll need our bypassing barn door hardware kit.


If your door requires a track length that falls between our standard 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 custom tracks.




Please call for custom track lengths and applications - 1-800-694-5977
