Capture interior or exterior vehicle-based shots with the G-51 Gripper Campod Suction Cup Car Mount from Camtree. Supporting camera rigs up to 22 lb while moving at speeds up to 25 mph or up to 44 lb for static shots, the G-51 can be mounted onto almost any vehicle surface including the hood, roof, side, or windshield.
This modular system is based on three sturdy suction cups, articulated legs, and a camera hub with a 3/8"-16 thread. It includes a camera hub with 1/4"-20 and 3/8"-16 camera screws, ball head connectors, and both 3 and 6" leg sections for maximum positioning flexibility. To maintain maximum adhesiveness, use the included dust covers to keep the suction cups clean and dust-free when not in use. Two ratchet straps and hardware are included for creating safety lines for the mount, and a soft carrying case holds all the G-51 components.
