Before ordering, please check your desk carefully. This under desk keyboard and mouse tray requires a flat, straight desk edge and a clear, unobstructed underside for clamp installation. It is not suitable for curved, rounded or beveled edges, or desks with drawers, crossbars or support beams underneath. The complete installation requires at least 31.3 inches of clear mounting width including the clamps. Please also confirm that there is sufficient underside depth for the tray to slide in and out without obstruction. Create a cleaner and more comfortable workspace with this practical keyboard tray for desk organization. The 25.6 x 11.8 inch platform provides room for a standard keyboard and mouse while moving them below the desktop, leaving more surface space for monitors, documents and other computer accessories for desk use. As a keyboard holder under desk, it helps keep frequently used equipment accessible without crowding your main work area. The pull-out platform works as a convenient keyboard shelf under desk, sliding forward when needed and returning beneath the desktop after use. This space-saving design is suitable for home offices, work-from-home setups, study areas, gaming stations and everyday computer work. Positioning the keyboard and mouse below desktop level also supports a more natural alignment of the forearms, wrists and elbows during typing. The no-drill keyboard mount attaches with sturdy C-clamps and fits desktops up to 1.97 inches thick. Protective pads help reduce scratches and improve grip without permanently modifying the desk. The platform supports up to 11 lb, making it suitable for standard keyboards, mice and common office desk accessories. For vertical mice, oversized keyboards or split ergonomic keyboards, please compare the product dimensions and available height clearance before purchasing. Correct measurement and desk compatibility are essential for secure installation and smooth everyday use.
