Rack dimensions?

[Mrgbb]

Hey all,

I am planin on building a adult rack for my bps and I was wondering if anyone can give me some dimensions fo a 6 bin 41qt tub rack.

Also where is the best and cheapest place to buy tubs?
And how should I wire the rack like what size flexwatt and should I do one long strip and snake it through or cut in sections or just do one strip of back heat? What do you guys out there prefer for an adult rack
and what kind of material should I make the rack out of?
I'm new to building racks I built a feeder rack but that is kinda different.

Thanks for any replies!
