I actually returned these cabinets and bought more expensive sturdier ones. The glides in the drawers are plastic rather than metal. As soon as you put files in them the weight causes the drawers to bend just enough to have the plastic glide slip off the rails. I was very disappointed in this product.
Get what you pay for I suppose. Drawers come off the with hardly any files even loaded. Two of them sort of work but hang off center when loaded. Other two are fully useless.
