These arms can be moved both vertically and horizontally. This allows for a custom fit for varying thicknesses of laptops and the freedom of not blocking ports or drives. A screen support and USB light are also available to accessorize the tray.

Also, the heater box may cause the system to sit higher than normal. Pole may be cut down by installer to lower kit. This will not void the warranty. May not work with swivel style seats for big rigs If the Tough-Tray™ Laptop Cradle is intended to hold a laptop or device while the vehicle is in motion, we recommend the Secure-N-Motion™ kit.
