Turning Knobs

The design of the turning knob is based on the ergonomics, which applies three petals that allow users grab the knob with thumb, index, and middle fingers and twist it with even force. This design makes turning the knob much easier, more convenient, much faster, and greatly reduce the time for closing and... deploying the light stand.

Moreover, the nut threads of the sleeve are specially designed since the outer surface of the nut has three layers of “propeller blades” for clamping the nut and the plastic part together, which helps reduce the possibility of thread stripping after a long period of use.
