The EI-7003C Universal Tripod Dolly from E-Image is a lightweight dolly with a capacity of 88 lb. and a working radius of 18.5 inches. The EI-7003C has mounts for both split-spiked and single-point tripod feet, making it virtually universal for all tripods. The single-point foot mounts can slide up and down the arm of the dolly to accommodate smaller tripods or to get a little extra height by moving the feet closer together. Each type of foot can be locked in place, either with a rubber tab (for split-spiked feet) or an adjustable, lockable clamp (single-point feet).
