Check Latest Price on AmazonWhich One Should You Choose?
If budget is tight → VIVO Small 20 x 11" Clamp-on (B0BPN6C2HZ). If you need a portable, no-drill solution that clears legroom → any VIVO clamp-on small or large tray (e.g., B08STGQZC6 or B0BPN6C2HZ).

Frequently Asked Questions
Will a clamp-on tray fit my desk with a beveled edge?
Most of these VIVO clamp-on trays are not compatible with beveled edges — they require a flat area to clamp securely. Check the product's desk-edge compatibility and measure the clamp seating area before buying.
How much weight can these under-desk trays hold?
These trays are rated around 11 lbs — enough for a keyboard, mouse and a few small accessories. Avoid loading heavy equipment or monitors on the tray to prevent damage or wobbly sliding.
Do clamp-on trays require drilling or special tools to install?
No — clamp-on models install using C-clamps and included hardware, so drilling isn't necessary. You may need a screwdriver or wrench for tightening, and assembly instructions are provided with each product.
