Spacing help with my rack

[bc30629]

I usually use 2-3 normal CDs under each corner of the tub(or under each end if making a 6qt tub rack). Gives enough space for the flexwatt and the tubs to breathe, especially after the rack settles.

AHh yes i was going to ask how many cd's would work. Three is a good number to go with? Its an adult rack with 32Qt sterilites.
