If you're really, REALLY serious about your work and looking to rig up multiple strobes*, LED lights, portable audio recorders, microphones, POV cameras, self-leveling lasers, or whatever else it might be that you'd want to attach to a standard 1/4"-20 tripod thread**, then this package of five Nasty Clamps is certain to help you out. As an added bonus, it's practically guaranteed that your friends, family, and clients will all end up asking you just "what the heck are those things?"
*Note: This Five-Pack of Nasty Clamps does not include 1/4"-20 to Hot Shoe Adapters, which you'll certainly want if you're looking to attach any sort of hot shoe mountable equipment to your clamps. These adapters are really quite handy (trust us, you'll use them if you've got them) and are available for purchase HERE on the Nasty Clamps site.
**Another Note: Officially, the heaviest piece of gear that you can place on a Nasty Clamp (without having the flex-arm bend) is about one pound (roughly 450 grams). Unofficially, much more weight than a pound can be placed on the clamp, just so long as the flex-arm is pointed straight up or straight down (i.e.: underslung). Just use your common sense, and don't mount a multi-thousand dollar piece of equipment onto your Nasty Clamp and then walk away. Again, use your common sense.
