Heavy-duty rigs are a version of rigs, designed to hold armatures and objects at longer distances. Even though it is designed to hold heavier objects/characters, its tension-adjustable joints could perfectly balance the joints’ strength and softness of their movements. With 4 arms extending about 30cm, M3 armature connector arm with a secure locking screw, and 6mm diameter rods, it mounts on a piece of wood or other media to securely hold armatures or objects.
