This large Hydra Alien Suction Cup from Tilta is a replacement unit for the one that comes with the Hydra Alien Car Mounting System, but it can also be used as an expansion accessory to the original rig. It works with any Hydra dovetail plate and can be easily placed in multiple positions to accommodate the majority of vehicles. The aluminum, stainless steel, and rubber suction cup can handle payloads of up to 110 lb.
