Measure your desk thickness and compare it to the product specs to ensure proper clamp engagement and stability.
Surface Dimensions
Verify that the tray surface fits your keyboard and mouse comfortably. Sizes range from 20 to 30 inches in width.
Ensure you have enough desk width to accommodate the tray plus clamps without hitting the edges.
Clamp Type and Design
Most use C-clamps but corner desks may need swiveling clamps. Avoid trays for beveled edges unless specified.
