We have a similar if not the same hardware. See: http://rusticahardware.com/industrial-barn-door-hardware/

We carry a brand called Leatherneck Hardware and have lots of experience with flat track sliding door systems. There are many many different options you have when you go with this type of system. Finishes, roller styles, stops, guides, etc. You want to make sure you talk with someone knowledgeable with this type of hardware if you are thinking about using it in a project. There are certain aspects you need to know, such as, these systems most of the time don't come with the mounting lag screws you see pictured. And you need to have your project blocked correctly behind the sheetrock because the tracks are predrilled(not every 16") and could be an obstacle when thinking about your project. If you have any questions please feel free to contact Derick at 952-935-0445.

We sell sliding barn door hardware. We are located in Idaho but ship our tracks all over the place. Our hardware is very high quality. We offer a variety of styles and finishes. We also specialize in custom orders. If you have a particular color in mind we own a powder coating facility which makes color options almost endless. The wheels on our tracks are unbelievably quiet, eliminating the grinding sound you hear with other tracks that use metal wheels. We see every single one of our products through from start to finish! contact us at http://www.basincustom.com or email us at info@basincustom.com or call 208-261-1270
