Craftsman 1000w Halogen Worklight
Tripod Light Mount
As you can see, the mounting flange for the portable light stand is a square u-shape that coincides with the shape of the base of the portable light stand. The knob on the "back" of the mounting flange is actually pull actuated not twisted as the knob shape might indicate and is the locking mechanism for the portable light stand attachment fitting. You have to pull it out and keep it pulled to allow the light stand to be installed. The same is true to remove it. Photo: Ryan King, 2006.
