I remodeled the walk-in closet by removing the door which was blocking access to cloth racks, removed the old rack hangers, fixed the wall, painted them and then build a new cabinet system with top lighting. I bought a couple different models of these rollers and decided to keep this particular one for the following reasons:
1. Can be made to fit the specific width of my barn door. Other models were based on a bigger wheel that could slide in and outward over a fixed rail. This model does not stick out further and I liked that (less of a trip hazzard)
2. Smaller wheel size looks better then some of the wheels of competitor products that had twice the wheel diameter.
3. It rolls smoothly and has held up for many weeks of usage by now.
I wish my barn door was just a few inches wider but I had limited space to work with. Overall I really like this roller and it is still going strong.
