Rack system

can anyone show me pictures CB110( i think thats what they are called) using hollow doors? .. a guy i know uses this and recommended them but havnt seen pictures it seem fairly simple and self explanatory but just kinda wanna see a visual on what some might look like. and would you recommending heat rope or flexwatt.. use heat rope atm but flexwatt seems to be what the main use is it just person preference? and is flexwatt hard to connect and setup on a rack properly

:snake:

I think a CB110 is the size of the IRIS brand tub. What brand rack are you looking at?

just planned on building one my own, out of hollow doors flats

You might want to check out Clay Davenport's website. He has a ton of blueprints with step by step instructions with pics. Hope this helps.
