The Libec is a TH-Z S4 KIT 40cm/15.5 inch slider and tripod system. The TH-Z Series is the successor of the LIBEC ALLEX series, now lighter in weight and with greater versatility. Similar to the ALX KIT, the TH-Z is fit for sliders thanks to its Dual Head design, however, this hybrid model is equipped with the industry standard TH-X sliding/quick release plate that is compatible with other brand tripod heads.
