Double Bypass Track Barn Door Hardware Kit Homacer Track Length: 180 in.

The package includes all the hardware kits you need to install a sliding barn door. Except for doors. The barn door hardware can be used both inside and outside. It is rust-proof waterproof and fireproof. The standard door thickness for our hardware is from 1 3/8″ to 1 3/4″. If your door thickness is not within that range please go to our second tab called “Customization Services” for more detailed instructions on how to customize it. The spacing between each hole is American standard 16″. Tracks 8ft and under is one single track instead of being connected by multiple shorter tracks. Tracks 9ft to 16ft will be connected by two tracks. Tracks 18ft and 20ft will be connected by three tracks. Therefore the spacing between the holes in the connecting section may not be 16″. Each complete track can hold door weights up to 220 lbs. For example if you have two doors that are each 30″ wide. You will need 2x 30″+30″ = 120″ long track. Or if you have an opening that is 48″ wide you will need at least a 96″ long track. The minimum clearance from the top of the door to the ceiling you need to install this barn door hardware is 6″.
