Steel Height Adjustment Kit Brackets for Computer Keyboard and Mouse Trays, Fits MOUNT-KB05A, MOUNT-KB05D, MOUNT-KB05E, and More, Black, MOUNT-KB5SP

They did the job, but I think they should have been free of charge.

These are perfect for the Vivo clamp on keyboard trays. The typical space with the default hardware on those is or becomes way too short under the desk, so that your keyboard barley makes it under when you push the tray under the desk. A mouse won't fit at all! BUT, with these height adjustable plates you can now add them to the keyboard tray and get a really good clearance for your keyboard & mouse! These should come automatically with those clamp on trays since everyones desktops are a different thickness. These are a bit pricey for what they are, but darn well worth it!

Me sirvio Justo lo que nesesitaba para ajustar la altura de mi bandeja del teclado se ve que es de muy buena calidad

Easy installation

Escelente.

Good on vivo for selling an accessory like this instead of making me buy a whole new keyboard tray. My keyboard was too tall for my vivo keyboard tray and this thing worked perfectly.
