Spring-loaded to create just the right amount of holding force, most tablets and compact laptops can be made safe and secure while on the go. The Tough Tray II is simple to install and adjust with retaining arms that ensure a perfect fit. If a compact laptop is in place, these retaining arms hold firm with the screen up or down and do not interfere with any ports or drives. Ideally suited for a multitude of applications and easily attached to hundreds of mounting systems for cars, boats, planes, and more. Includes laptop tray, standard retaining arms, and flat retaining arms (that allow laptops to close while in the tray). Constructed from high strength composite material. Adjusts to fit laptops 8.5"-12.3" wide. 1"H x 6"D.
