Review on 🚪 TE DEUM 6FT Sliding Barn Door Hardware Kit - Heavy-Duty, Sturdy, Smooth, and Quiet - Easy Installation - Fits 36in Wide Door Panel (I Shape Hanger) - Improved SEO by Phil Prater

They are quite good quality for the price. Our problem is that the holes in the track are a fixed distance apart, and while the spacing between whole pieces is standard construction points for framing an interior wall, I think it's likely that 50% of the time it's misaligned Zimmermann has drawn the distance between the studs from left to right or from right to left. I ended up just buying new bar stock from Lowes, drilling the holes to my specifications, and spray painting them with a few coats of matte black spray paint. Aside from cutting out part of the drywall, putting shims between the studs, and fixing the drywall when you're done, the extra expense of a new bar worked better for me.
