Height Adjustable Clamp and 12 in Rail Set for Under Desk Keyboard

In this review of the VIVO Height Adjustable Clamp and 12 in Rail Set, the bottom line is simple: this kit is for DIYers who want to convert a personal wooden board into a sturdy under desk sliding keyboard tray without drilling into their desk. The single biggest reason to buy is its clamp-on, height adjustable design that enables ergonomic placement and a smooth slide while protecting the desk surface. Assembly is straightforward and the kit ships with the slider tracks, C-clamps and all required mounting hardware.

Key Features

• DIY Customized Design: Lets you transform a board at least 10.5 in wide and 0.6 in thick into an under desk tray so you can reuse a preferred material and finish.
• Height Adjustable Brackets: Provide 2.4 in of total height adjustment with five set points for fine tuning typing angle and position.
• Sturdy C-Clamps: Clamp firmly to the desk up to 1.75 in thick and tighten by hand, avoiding permanent desk modifications.
• Scratch Safe Padding: Anti-skid padding on the clamps protects the desk surface while holding the tray securely in place.
• Complete Hardware Package: Includes two 12 in slider tracks, two C-clamps with padding and all mounting hardware for a ready-to-install setup.

Who It's For

This kit is ideal for home and office users who prefer a custom wooden keyboard tray or already have a finished board they want to reuse rather than buying a prebuilt drawer. It suits people who need adjustable height options and a clean, non-permanent mounting that preserves the desk surface.

It is less suitable for users whose desk edge exceeds 1.75 in in thickness or those who need an integrated under-desk system with an included manufactured tray; this product requires a separate board (tray not included) and supports up to 11 lbs.

Pros & Cons

Pros

• Solid build quality and sturdy clamps give confidence that a keyboard and small accessories are well supported.
• Height adjustability with multiple set points makes it easy to dial in ergonomic placement.
• Easy to assemble and install with included hardware and hand-tightening clamps.

Cons

• Requires a separate keyboard tray board that meets size and weight limits, so additional material and work are needed.
• Desk thickness limit of 1.75 in excludes some thicker desktops and workstations.
