I started a new design rack for my gilas it's a aluminum bolt together system that can use V35 or V35s for short tubs each shelf can be adjusted for tub spacing or different tub can also use two different tub at one time very useful.tub slide out on rack and belly heat is provided in back I also made it to accept castors directly in uprights what I love the most is it's so adjustable to an needs even side walls can be inserted in without disassembly.
