Combo 7 is everything you'll ever need to position a flash as you need, be it on the Sidekick, the Wimberley Head, directly attached to the quick release plate of the tripod collar, etc. As with all of the Shape Shifter components, and unlike other manufactuerer's products, parts are captive to prevent detachment and from accidentally unscrewing them too far while in the field. Total weight of this combination is 1.58 lb.
