WINSOON Sliding Barn Door Hardware 18ft Track Single Door Kit Low Ceiling for Garage Closet, Big Spoke Wheel Roller

I needed 24' of rail since my door was 12' foot long. I bought a 18' section and a 6' section. The hardware arrived and I was pleased with all the components, it was very sturdy material. Since I did not have enough rail connectors (needed 3, had 2), I had to fabricate on, but I knew that going in.The holes on the rail are 16" apart UNTIL you put two rails together, then you loose that spacing. Since I was putting 4 rails together I lost my 16" spacing. I had to redrill more holes on one of the rails to hit the studs. It was not a problem over the door header, but on the wall it only matches up for the first 6' section.I also had 4 rollers to support the door. Getting those to be EXACTLY on the same plane so it sits on the rail properly was a challenge. To do it over again I would mount the two outside wheels first, put up the door and then mount the inside wheels.Overall, I'm pleased with the install, took longer but looks good.

Quick delivery, usps…sturdy and solid.
