The jaws can handle a pipe about 1.5 inch in diameter so that's perfect for mic stands, tripods, and handlebars. The clamps are noched rubber pads so they grip really well once you have them tight. These have a small rachet arm you can lock down once you get the angle you want. The head is a standard 1/4-20 threaded head meant to fit any camera or any of our Nootle Tripod Mounts. We sell these stand-alone for anyone who needs one of these for their cameras or if you already own a Nootle iPad or iPad mini Mount. You can also buy these with various mounts to get all the function needed at once.
