Discover Tackform's innovative mounting solutions, designed to cater to your dynamic and versatile needs. Our 4.75" Pump Suction Cup is the perfect choice for securely mounting phones, tablets, and action cameras, especially in mobile environments like off-roading and auto racing. It accommodates arms up to 7” long, but for more aggressive environments, shorter arms are recommended, while longer arms can be used in stationary settings. Included in our lineup is the specialized 20mm Ball, crafted for seamless integration with Tackform's 20 Series Platform. This system is centered around a robust 20mm ball and socket setup, ensuring a secure and reliable mount. However, it's important to note that this ball is NOT compatible with 25.4mm/1”/B-Sized sockets. The main housing of our Pump Suction Cup is CNC Machined Aluminum, featuring three Type B interface mounting points, allowing you to mount up to three balls simultaneously. (ONE INCLUDED IN THIS KIT; ADDITIONAL BALLS SOLD SEPERATELY). For those who prefer custom setups, there's also an integrated Diamond mounting pattern, providing flexibility and compatibility with a range of gear. This design ensures easy adaptability between different ball sizes, enhancing cross-platform compatibility. At the heart of Tackform is our American heritage.
