    Quick Release Clamp with Metal Knob is rated 4.8 out of 5 by 5.
    Rated 4 out of 5 by from Well made - perfect for monopoles Wanted to be able to quickly switch my camera from my tripod to my monopole - both Vanguards - but needed a quick release Arca type mount for the monopole. I have a Vanguard ball mount on my tripod. Adding this took care of my problem and it adds maybe a 1/4 of height. Sure wish it was lower cost as can purchase a very nice monopole for the same money. Also wish it had the safety pin to retain the mounting plate so don't have to worry about the camera sliding off if the knob gets accidentally lossened. I have not had this happen at all but just would be nice security. It is a well made product that works great.

    Rated 5 out of 5 by from Excellent option for reto-fitting I bought this to add an Arca-type QR system to my existing Bogen Midi ballhead (#488, I think). I attached it to the existing camera platform using red Loctite. After letting it cure, I put it through its paces and it's fantastic. Precisely-manufactured, the quality of finish is superb, operation is as simple as can be, and I can't imagine how it would ever fail or become unreliable except through user error or massive damage to it. Great choice for retrofitting ball heads that one cannot remove the camera platform from before adding a QR clamp. It opens far enough to allow one to set a plate in directly from above rather than slide it in from the end (which is tedious), and the knob tightens quickly. Great product, you can't go wrong with it if it fits your needs.

    Rated 5 out of 5 by from quick and easy I use this on my monopod to make lens changing a snap. Why have QR plates on everything if you need to remove them to use a monopod, just make life easier and get a QR clamp for your monopod too. Quick and easy to use and clamps firmly.

    Rated 5 out of 5 by from Great Clamp I purchased this clap to attacked to my Manfrotto 488 ball head which had an existing 3/8 stud. I am very impressed with the fit and finish of this part. It went on right the firs time and have had no issues to date. The screw works exceptionally fast and allows for fast camera attachments. My only regret is that I did not buy one slightly wider.

    Rated 5 out of 5 by from Works as advertised I put this adapter on a monopod and it works great. It's very simple to install on a tripod or monopod, and it works flawlessly.
