I was looking for a clamp to use on my tripod when taking pictures and found this.

This is probably the nicest clamp i have. Its beautifully machined and has no sharp endges. It has a well thought out design that allows for many uses.

The clamp has about a 50mm opening and it take about 4.5 rotations from fully closed to fully open. The lip of the jaw to the adjustment screw is 40mm, so that is the deepest it could clamp on to something. The jaws have 1/4" threads that go through the clamp jaws and 2 on the back, so you can put the arm on 10 different positions on the clamp. The large ergonomic tightening screws are rounded and comfortable.The clamp its self weigh 125.9 grams

The arm is 105mm long not including the threads. It has a two ball joints that tighten on a single screw. The precision allows to make fine adjustments and tightening is easy. The o-rings are there to assist with the fine tuning and it has a very smooth action. The arm weighs 95.1 grams

Over all i am impressed with this. It feels like a well made quality clamp. Also, for the price it is fantastic.

This clamp isn't great flat surfaces, it's made to grab onto poles.
