Flexwatt one long thread vs multiple strips for a rack

[notmyfault]

I'm planning to build a 4 tub rack using melamine pretty soon and I just have a few concerns.

How much space should I leave between tubs and shelves? I've seen people use CDs as a guide. Is this a good guideline to use?

Also, it safe to thread one long piece of 4 inch flexwatt throughout the rack for belly heat? Or is it better to run multiple strips of flexwatt on one power strip recessed into the shelves.

I was thinking it would be okay to just use one strip, but would this be a fire hazard in the long run?
Which is the safest?

Any other suggestions to lookout for?

Thanks in advance.

I use one piece per shelf JUST because if there is ever a problem, all I have to do is remove the back of the rack and replace the one piece that is worn.

Running one piece is probably less of a fire hazard due to there only being two connections that you can screw up, instead of 20 or so.

I think its better to have individual strips. It's easier and cheaper to replace one strip than the whole strip. Also its safer to solder your connections than use those plastic clips.

I was thinking of buying one long 4 inch strip pre-wired from RBI. I'll have to ask Rich what his opinion on the matter is also before I make my decision. Thanks for the input guys!

I do both. Both work fine and are safe. There are ups and down for either method. It's easier to use one long piece, but its harder to replace if there's a problem. Vice versa for multiple flex per shelf. I personally like the one long thread better. It only takes one connection to plug in.

Also cd spacing is perfect
