Hi, I am rebuilding my shed that is attached to the garage. It’s 20 feet wide, and 8 feet deep. I’d like to put a 6 ft sliding barn door, but need advice about a good quality exterior hardware kit. I‘m Not looking for something stylish that will degrade in a season. I want a well made good quality steel roller system that is easy to install and will live up to outdoor use! Any suggestions? I’ve browsed a lot, and see mostly interior products...
