Before buying an under-desk keyboard tray
A keyboard tray can clear the desktop and change wrist and elbow position, but fit is mostly a measurement problem. Check the desk edge, usable underside space, knee clearance and the tray width before buying.
A practical checklist
Measure desktop thickness; inspect braces or drawers under the desk; confirm knee clearance; compare tray width with your keyboard and mouse; leave enough room for the mechanism to slide.
VIVO Black Clamp-on 27 x 11 in Keyboard Tray, MOUNT-KB05E
Amazon currently lists this VIVO clamp-on tray as a slide-out keyboard-and-mouse platform. It is worth comparing if you want a removable clamp solution instead of drilling into the desktop.
Before buying: Measure your desk edge and underside first. Clamp-style trays will not suit every desktop shape or thickness.
