Package includes all the hardware kit 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, water proof and fire proof.
The spacing between each hole is American standard 16''. Tracks 8ft and under are 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 weight up to 220 lbs.
Usually we recommend the track length to be at least double the total door width or the opening. For example, if you have two doors that are each 30'' wide. You will need 2* (30''+30'') = 120'' long track. Or if you have a opening that is 48'' wide, you will need at least 96'' long track.
The minimum clearance (from top of the door to the ceiling) you need to install this barn door hardware is 6''.
