Hey. I'm debating on getting a bunch of Iris uc-601 for a rack system for my balls. I have one drawer, not in use atm, but today I'm testing escapability with my escape artist girl. I'm mostly worried about heating it with heat tape and if it's big enough. They're not flimsy and crappy like most stackable drawers, which is only reason I'm even considering them. If you know someone who uses or used these, have a link, or any information on using these for snake racks, it'd be appreciated, thanks!
