UltraClamp Assembly Camera Mount Accessory for Cameras, Scopes, and Binoculars

hello, this pedco ultra clamp assembly is wonderful. it can clamp on to just about anything you can imagine. it has a non slip safety screw to keep your camera mount tight and not come loose during filming. if the fully adjustable mount is not your style or gets in your way, you can unscrew it completely off and just use the clamp section by itself. The clamp section has its own camera screw in mount. it attaches to boat stanchions and different types of handlebars with ease. the design is outstanding. the delivery service from amazon was extremely quick as i ordered it on monday and it arrived on tuesday afternoon. it was the normal "prime" two day order and not the extra $3.99 one day service. outstanding amazon guys, you rock!update: jan 17 2012 i have used this clamp with several different types of digital cameras and a camcorder. as long as the camera has the standard screw hole on the bottom, this unit works well. i can mount it anywhere there is a tubular rod or smooth edge to fit the clamp. for the tubular rods, the clamp has a small v groove cut into it and that makes the tube fit right into the clamp. this allows excellent grip and when tightened, is very secure. the clamp itself has rubber pad for a non scratch grip. the still photos on a sailboat are very clear and the videos are outstanding. now, if i can get functioning remotes for my digital cameras, i would be in business.

This is a great product.It is made out of high-quality strong impregnated plastic and the clamp part is metal with rubber covers where it actually clamps on. This can clamp anything from a glass car door window to wooden or metal fence post or slat. The clamp part comes off so you can use just the top portion screwed onto any 1/4 x20 stud ore even a small tri/bi-pod.I've used this on both my bicycle and motorcycle. It clamps securely to a frame member, handlebar and even a brake master cylinder reservoir. It seems pretty darn solid and I've never had an issue with it falling off. Still, I loop the camera strap through a mini carabiner as a back-up. That's why cameras have a strap in the first place -as a back-up.The top portion is very adjustable and the two ball-joints give almost infinite adjustability. Once the setting thumb screw is tightened down it is SOLID.I've heard a few complaints that the screw is easily stripped. Come on folks, you don't need to tighten this thing down like a GORILLA. People tend to seriously over-tighten fasteners of all types. This is made out of a strong high-impact plastic but it is still plastic. It tightens down very securely but if you bear down on it like a GORILLA you are going to strip it. You can strip any fastener -even a metal one by over-tightening. It's only a 1/4 x 20 screw in there that is molded to a plastic thumb handle. If you strip this out then you are OVER-TIGHTENING it folks.The fact that it comes apart makes it not only more handy with more options to work with other gear but it fits into a smaller bag when it is in 2 parts. This is how I carry mine. The thumb wheels make it fast and easy to put back together or adjust.I can't say enough good things about this product.Cons:None, unless you are an oafish GORILLA who over-tightens things to the point that they break. 300 ft-lbs will strip just about anything out.

I was pleased with the quality of this clamp when it arrived (I bought 2). I have seen a number of cheapo clamps and based on the reviews here decided to take a chance. For my use case, it does the job well.I am actually using a pair of these to mount a Vizio VSB200 sound bar to my treadmill. That sound bar is just a touch over 12 pounds, so I am at the published maximum limit of the clamp. As one of the other reviewers mentioned, you can't treat this like a cast iron C-clamp. It is made out of aluminum alloy, which keeps the weight down and the design does a good job in the compromise between useability, strength, and weight. If you crank down on the screw, the clamp WILL flex. That's simply the nature of physics with the material and C-clamp designs. I didn't find the flex unreasonable for the target weight zone.Were I to change something about the design of the clamp, I would change two things. First, I would change the ball clamp material to something more rigid. It works fine and will probably be fine forever. I'd just like a bit less flex in that piece. Second would be the material used for the protective covers (screw and opposite clamp arm). They are a little to "slick" for my taste, so I would make them rougher or stickier so that they slide less.Bottom line is that I would still buy this again for the same use. I would have no concerns using this as intended for low weight photographic/av equipment.
