This is an excellent 19" rack 2U slide-out drawer and the quality is very good. The approximate internal dimensions are; width: 433mm (17"); depth: 347mm (13 5/8"); height: 70mm (2 3/4"). The main reason why I went for the Thon drawer over the others is that the rails are on the bottom and not on the sides, which gives you more width. I use it to store my 15" Samsung laptop, which just about fits in width-wise with the side power lead attached. I'm going to purchase some right-angled adaptors for the power and USB connectors, so I can use the laptop with my Kemper amp and the audio interface for my D.A.W. The drawer has a full-height lip at the back which has two cut-outs, left and right, which enables you to pass a power lead through. The side lips slope down from the back towards a smaller front lip. I installed the drawer into a Samson SRK8 along with a pair of lockable Thon 2U and 4U drawers. I now have a very neat storage solution which I can wheel about and it allows me to store all my gear in one place. I have also attached a 1U rack mount power strip at the back, which means I only have one 13 amp UK plug to deal with. Overall, I'm very pleased with the Thon rack mount 2U side-out drawer and can highly recommend it.
