The gray black DocZ2 Foot Stabilizer for Monopods from 3 Legged Thing can mount to compatible monopods via its 1 4 -20 threaded mounting stud, but a 3 8 -16 stud adapter is included for monopods with a larger socket at the bottom. This foot stabilizer is designed to add stability to the support, and with its rubber boot friction control it creates a smoother pivot when shooting a video or tracking a fast-moving subject. Also, the adjustable ball locks into place, and the foot has a load capacity of 44 lb. This 1.1 lb stabilizer has an alternate use as a mini or tabletop tripod with rubberized feet that add traction on smooth surfaces or a better grip on uneven ground. To store, the 3.5 tall tripod s feet fold upward to a compact 6.5 .
