The Quick-Set Hercules is a quick-release mounting system for a big camera… very big. The plates are 10x14cm, and the clamp itself is 12x20cm- so this is not something you want to attach to your travel tripod. But if you have a big camera (very big), this might be what you’re looking for. Attaches to a tripod via a 3/8 thread, or you can screw it into a mounting surface using the pre-cast through holes. Cameras are secured to the plates with standard tapered-head screw (not included). All metal, sturdy as heck. Choose style below.
