The Kupo hostess tray kit is primary designed for perfectly sliding an aluminum cheese plate (10” x 14“ ) into the framework between rubber seal and window of vehicle for mounting a camera or holding other equipment. To ensure the stability of tray, the offset support can be easy set up from the combination of suction cups, grip heads and 5/6”(16mm) baby rods. Two safety rope ratchets are also included to make sure the tray won’t be popped out when hooked around from window and suction cups. In addition, this simple set up provides a great operating environment where you can get in and out of the vehicle without the inconvenience of dismounting the tray.
