Matthews Vacuum Pump Cup 10" 417023 is a heavy-duty style vacuum cup. Pump until the red marker disappears to create an amazing bond to nonporous surfaces such as car hoods and doors.
Use in conjunction with the 4-Way Tilt Plate for interesting camera angles and a camera tie down strap to ensure proper safety precautions.
Should you require a smaller vacuum cup for mounting your lights or camera, then the new 4-1/2" cup is recommended to fit into those tight places when either the 10" or 6" vacuum cup is too large.
