50mm Aluminum Universal Screw Knob Clamp Quick Release QR Clamp 3/8" w 1/4" Adapter with Gradienter, Compatible with Arca-Swiss Standard Tripod Monopod Ballhead

Well made and simple. No frills, but you don't need any for a quick release plate.Ended up buying a second to keep on my monopod.

I got this to make an occasional use adapter. I screwed one of my Vanguard qs-39 quick release plates to the bottom so I can quickly convert my sbh-250 ballhead to accept Arca Swift. It works. Disappointed in the side levels. They are off a little bit but it doesn't matter because you can't really see them anyway without a bright light. They are recessed and covered with thick plastic. They don't catch the light and glow like you would expect a bubble level to do. In my use it does not matter because my original clamp is still in place and has nice bright levels. If I were permanently converting my head, I'd get something with better levels.

I have 3 of these and they are all great so far. It's the least expensive unit that has good ratings AND comes with a threaded body, a thread insert adapter and a threaded bolt included. So with that combination of parts you can attach this in a variety of ways to pretty much anything you would realistically run into.The clamping knob is also long enough to clear flat surfaces like the top of a stabilizer. I recommend this unit.

I use this for a camera mount to a rail system and it works perfectly. The parts are very nicely machined, fitting the right screw size and the Area plates just right. It tightens down perfectly, with a nice feel to the dial. I'd certainly buy another.

Great price.

Great product. Very well made. Clamp is high quality and clamps very tightly. I use it for a rifle mount and it holds 20 pounds just fine.

Exactly what I needed! My peak design plate is compatible with this, and this has made my life much easier.

Worth every penny
