Fits great.
Multiple iterations of this dock have wires coming out both the front and back, making it ugly on the desk and no way to hide wires well. Mounting under the desk with this helped a ton, looks way better. Perfect fit.

Easy to install for clean under-desk mounting
Fits my Dell WD19TB dock perfectly. Great for under-desk mounting (just be careful if your desk surface isn't super thick - you may not want to tighten the screws all the way)
