Review on Heavy Duty 12Ft Double Sliding Barn Door Hardware Kit - Smooth & Quiet Operation For 36" Wide Doors - J Shape Hanger Black | SMARTSTANDARD. by Justin Spence

I love this product. It's rare you get something these days that's well constructed, but this thing is amazing. The doors pictured are done with tile, backer board, plywood, mastic, grout and 5/4 board pressure treated wood. And 14 gauge metal on the backside. During each phase of the build, they got heavier, and heavier and heavier. Honestly, I'll bet they're 175 pounds. Each! I was worried that this system might not support the weight. Not only did it support the doors, but I've also grabbed the rail with my hands and hung from it, (I'm 160 lbs).with the doors hung also. This thing didn't budge. I'm not suggesting overloading the system. But if you do, it'll be fine. And when they're heavy, it's suuuuuper smooth. Getting ready to order another kit right now for inside the house.
