The Slik PRO CF-634 Tripod Legs have 4 sections that make the tripod easier to travel with than the 633, as it compacts to 18.7". However, it also adds a little weight and gives back a little height. This is the result f the overlap of the leg tubes where the tubes join. Maximum height is 62.6", and weight is up to 2.1 lbs. The leg locks are the twist collar type, but the Anti-Rotational System legs keep the leg sections from rotating inside each other, so the lock is easy and positive. The carbon fiber leg tubes are comprised of 8 layers of interwoven carbon filaments which are then bonded together.
