This casted aluminum tray can be screwed onto any standard tripod for use in the field, warehouse and places alike where a highly mobile laptop is needed while standing. This tray has a standard 1/4-20 screw pattern so it can be screwed onto anything with this thread. Great for those looking to make a DIY laptop holder in your garage, office and more. Two velcro straps are included for securing the laptop. Holes in the tray top allow for good ventilation to your laptops cooling ports. The padded front lip keeps the laptop from sliding off and also protects it from being scratched.
