Within 3 minutes I had this on a door and was using it with my camera to fashion a makeshift slider. Absolutely brilliant product. I will be using these (yes I will buy a lot more) to make lighting rigs, attach ball heads (B002N5CV8Y
to and to use with lighter weight cameras - absolutely superb piece of kit.
It is now acting as a firm second film camera rig for two camera interview shoots; ad hoc light placement and a many other ideas that I can dream up. One of the best purchases I have made for filming. Highly recommended.
