Buying Guide
- Desk compatibility: Check total clamp-to-clamp length and desk thickness limits. Ensure the desk edge permits full extension without hitting obstructions.
- Ergonomics: Look for tilt options, height adjustments, and slide-out reach that align your keyboard and mouse with your natural arm position to reduce strain.
- Weight capacity: Most trays support about 11 lbs. If you use a heavy keyboard or add a mouse, verify the rating and balance with clamps and brackets.
- Rotation and storage: Consider whether you need 360° rotation or under-desk storage when not in use. These features influence available space and placement flexibility.
- Installation notes: Some trays require thicker desks or specific edge shapes; ensure compatibility with beveled or beveled-edged desktops.
- Maintenance: Look for smooth-glide rails and durable clamps to maintain performance over time and reduce wear on desk surfaces.
