Did my post confuse you JG? sorry if it did :-) .. Gosh I hope everyone would use common sense with the height.. but maybe not.. Sorry if I have confused anyone.
What I meant about the 2inch pipe is not the height or how much space but I was saying ,in a sort of thinking out loud way ;-) the plastic tubing/piping
I use must be about 2inches meaning it sticks out that much from the side , as in how much of a ledge it gives. I keep it tight to the edge so no little feet or anything can get between it.
Hope that makes sense. I didn't want to give any height guidelines , I just assess it as the days go buy and move as required.
