The KP100LE Adjustable Keyboard Tray Platform from 3M is a standard all-in-one platform with wooden construction that minimizes bouncing. The mouse surface can be placed to the left or right on this platform. The KP100LE tray is equipped with a gel wrist rest with anti-microbial product protection. Anti-microbial product protection inhibits the growth of microorganisms, such as bacteria, on the product surface. This prevents stains, odors, and product degradation. It is a replacement adjustable keyboard platform that works with AKT170LE, AKT91LE, AKT90LE, AKT71LE, AKT70LE, AKT65LE, and AKT60LE keyboard tray models.
