Little tip for those using melamine for diy racks...

I've used 1/4" dowels, but other than child proofing racks, is any of this neccesary? I've never had a tub move forward on me.

I think it would help ensure that they're all the way back. A couple of times I have carelessly not pushed a tub far enough back and left a very small gap. Luckily I caught it before anything happened, but if you had these and made sure they were "locked" wouldn't have to worry about not pushing all the way.

But, you're right, I've never had one slide forward on its own accord (or the snakes).
