Nice, what are the details on the rack you're building? Tub sizes? Materials? I'm going to build a new rack too as I recently ran out of space, ironically my heat tape order showed up today too so that's ready to go and I stopped in the local sign shop and order a 4x8 PVC sheet cut to the sizes I need to make a 7 tub rack (28 quarts Vision tubs which arrived Monday).
