The 6" Suction Cup With 3/8"-16 Stud from Matthews is a super-strong camera and lighting support designed to securely mount your equipment to any flat surface. The cup features a simple-to-use integrated pump system which creates an air-tight seal between the suction cup and the chosen surface. Simply press the pin inwards to create the vacuum seal and when the red-line disappears - you're ready to go!
The top of the cup has been fitted with a common 3/6"-16 threaded stud to accommodate most standard tripod and monopod heads, giving the user a wide range of choices when it comes to camera movement and positioning. When using this suction cup on a horizontal surface Matthews recommends a load capacity of no greater than 20 lb, however, when used on a vertical surface weight capacity varies based on the size and weight of the equipment being used. All users are recommended to test the stability of the suction cup on a given surface before mounting heavy equipment.
