Mount these Wheel Set for FGS-900046 Heavy-Duty Stand from Steadicam on your heavy-duty stand and roll along flat surfaces to bring and balance your vest/arm-type rig. On interiors and exteriors, the wheels facilitate moving your setup without having to pick up or fold your stand when adjusting the position. Plus, you can roll your stand with your stabilizer rig on the stand for added convenience. The 4" wheels provide smooth rolling on hard surfaces, and the integrated foot brakes are easy to actuate, so the stand won't roll away. Please note that these wheels are not compatible with American Grip products.
