Your review: I bought some of these lids and folding crates to use as a tool crate for our install crews. We wanted something that was easily ship-able and could be locked. The only thing is that the lids and crate don't have a provision for that so I had to drill holes for steel cables. Other than that they were great for what I needed!
Pros: Can be folded and stored, lockable with some modifications.
Cons: No way to lock the lids to the pallet in stock form.
