Yes, I’ve tried them, and unfortunately they don’t work with the L4500. The depth isn’t the issue, it’s the inner rails that don’t extend out far enough, so the last 2 inches of your chassis are stuck inside the rack. If you don’t have anything in the 1-2U directly above it, you might be able to sneak the lid off if you wiggle it back and forth a bit, but otherwise you’d need to pull the chassis completely out every time you need to perform maintenance.
