The unique triangle shaped center column allows for a more compact design as well as a sturdier center section. Inspired by the principle of Triangle Stability, the ST tripod includes a triangular carbon fiber center column that successfully challenges the classic round shape design. The center column can be reversed to achieve ultra low shooting positions. 1/4" and 3/8" screw ports allow for connecting two accessories at the same time. Features: Quick Install & Detach Upgraded side loading plate with safety pin and flip lock. Safety pin is designed to help prevent the equipment from accidentally falling off when the equipment mounted on the plate is moved back and forth. Huge flip lock for easy operation. Use the Allen key to fine adjust tightness of flip lock. Fluid head provides smooth and accurate operation to help create high-end videos. Moreover, this head works well with tripods, sliders or other accessories to meet different shooting needs. Handle can be mounted on either left or right side for comfortable operation. Tilting range from -60Adeg to +90Adeg provides various shooting angles. Built-in handle makes it easy to adjust shooting angle. The Arca-type base and 1/4"-20 threaded socket allow you to quickly switch between different heads and tripods.
