23-215 Bypass Bottom Guide Assembly

I have 3 standard hollow core closet hanging from 2 overhead tracks to conceal a storage area. I need something to keep the bottoms aligned. Your mirrored door tracks look like what I need but I would like some more information on your 23-215 guide assembly, perhaps installation instructions if available.

Looking at the picture, the center guide appears to be nylon or similar, is it spring loaded to adjust for uneven floor tracks as the doors are opened/closed? My doors are 32" wide, would 1 guide be sufficient on each door? Would there be a binding problem with 2 on each door?

Many thanks for your help!

I am already using floor guides and they are not satisfactory. With two bypass doors on a closet, the doors stay in constant contact with the guide. In my 3-door installation, the doors move from one guide to another as they open or close and with the inherent slop in the system from the overhead tracks and hangers and the pull on the door to move it, it is as likely to collide with the next guide as pass though it.

I know I could work around this by installing more guides but that brings up another problem: stepping on one of the guides in the dark is a less than thrilling experience.

If your 23-215 guide works the way I think it does it should be a good solution with the floor tracks, I just can't find out anything about it or how it works

Many thanks, even it wasn't what I wanted to hear. Guess it's back to the drawing board.
