The Cobra Wheels from iFootage are a pair of clamp-on wheels designed to convert any object with a 16 to 32mm diameter into a makeshift dolly. The wheels and clamp are constructed from aluminum with steel components, making them capable of supporting up to 88 lb. Each wheel has a diameter of 2.3", and the entire assembly weighs just 9.9 oz. In addition to the assembly's clamping function, the clamp features two female mounting threads — one 1/4"-20 and one 3/8"-16 — allowing for the attachment of additional accessories.
