The ST-Z is the short centre column for SIRUI ST-124/125, ST-224 tripods.
The 10-layer carbon fibre centre column allows for low angle shooting as the legs of the ST-124/125, ST-224 tripods can be splayed out to get the tripod low to the ground.
The reversible tripod screw in the mounting plate can accommodate tripod heads or other equipment with a 1/4 or 3/8 inch thread.
