Keep in mind they will "flex" at top with water in them. So the 20" top may end up at 22-23" depending how much water is in them. Didnt bother me in my wide open rack stands. Actually did allow for more water backflow during clean up. Structurally sound either way.sweet. I’ll be grabbing one of these soon. Thanks!
If that bothers you. You can put a simple ratchet strap at top of tote to keep it tight and from opening up on you.
