More Info



Lag bolts are not available for Heavy-Duty Stainless Box Rail. To guide the door at the bottom, upgrade to the Industrial Floor Mount Stay Roller (not available in stainless, comes in unfinished steel).


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.

Bypass Doors for two doors:


Soffit Mounted: For bypass 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.


Wall Mounted: Bypass doors slide in front or behind each other, and can slide in front of the wall next to the door opening. Measure the width of one of the doors and multiply by two to determine your minimum track length. For example, if you have two 3-foot wide doors, you will need a track at least 6' long. For help determining the track length you will need for your application, please call us.


Bypass Doors for more than two doors:


Soffit Mounted or Wall Mounted: Several doors can be placed on the two parallel tracks of the bypass system. Often, people will use three doors, putting two doors on the front track, and one door on the back track (or vice-versa). Please call for assistance determining the kit you will need.
