Which roller is best for my closet?
Hello! The only difference between these rollers is the design of the wheels, which I unfortunately can't make out from your photo. The 23-086 and 23-070 are both concave, though the 23-086 specifically has a ball-bearing wheel. These are interchangeable, though I favor the 23-086 because ball bearing wheels are better.
The 23-081 is a convex wheel and not interchangeable with the other two.
You need to check the style of your wheel to garner whether it's concave or convex. If it is concave, you just need to decide if you'd rather have ball bearing wheels or not. They work better but cost more, so that's basically what you're deciding on.
