The FS PRO SM1 suspension arm is now lighter and can support cameras of 5 to 20 pounds (2.27 to 9 kg). (Note the possibility of adding counterweight of 1.75 lb/0.79kg to the sled, which allows it to support cameras of less then 5 lbs).
Both parts of the arm can be adjusted and are equipped with a made-to-measure spring, allowing the operator to move the sled up or down almost effortlessly. The springs contain a high level of carbon, which gives it a maximum rigidity. The suspension arm is also equipped with 24 all-new sealed ball bearings that allow it to move with a higher fluidity.
