Review on Enhance Your Space with DIYHD 6FT Brushed Sliding Barn Door Hardware Two-Side Mechanism and Soft Close Kit by Brandon Carraway

These rails looks great and seem to work pretty well so far. Bearings on the wheels roll very well. A couple of notes for future builders:1. The instructions are in metric units. I needed to convert some measurements in the instructions from metric to make sure I had the right tools and drill bits. After that, I measured the whole thing with a metric tape measure. Screw up a conversion and you're going to be unhappy.2. You'll need at least 8" of wood behind the drywall above the doorway. The outer rail brackets are pretty high up there.3. The door must be between 1 3/8" and 2 1/4" thick. Thinner doors mean a bigger gap between the doors. Plan accordingly.4. Because the bearings on the wheels roll so well, keeping the tracks level is VERY IMPORTANT. You don't want coasting doors!5. Metric tools would be helpful too: 13mm box-end wrench especially, or better a 13mm socket.Overall, an awesome product to finish an awesome project.
