New rack built have a couple questions

[snj35]

Here is my first rack I built off of what I seen others doing on here. I need info on how to make the rack sturdy so it doesnt shake, should I put brace under each shelf so it doesnt shake or warp , how many holes do I put in the sterilite containers. I live in south fl and the snake rack will be inside my house when its all done

You can put peg board on the back of it. That will hold heat better also.

I put a piece of melimine wood for the back part. And the rack does not move. Its super strong.

I use 1x2 along the back, it will help make it sturdier and will also prevent the tubs from sliding to far back.

Just for anyone else... I would run in this case three, 1x2's vertically along the back side of this rack which should help stabilize it some and also prevent all three of the top tubs from being able to slide out the back side.

When i made mine i closed the back of the rack and use back heat it works awesome the heat stays at 88 all the time
