PX7 7 inch Arca-Swiss Double Dove Tail Type Plate

I bought this with a C60 clamp to create a flexible nodal rail. Very nicely made, quality stuff, reasonable price. It works just how i wanted. Maybe my ignorance, but I think It should come with some instructions. There must be a lot of optional uses, e.g. I am not sure what some of the screws are for. One side (the side I wanted to use) has no measurement labelling.

As an owner of other products I had no reservations of ordering this plate for my canon 500 f4 lens. The build quality of everything they make is hands down BEST!

I contacted ProMedia Gear on Weds., 8/16/17 in need of a long plate to mount a heavy rented Sigma 150-600mm lens to shoot 2017 Total Eclipse on 8/21/17. I have purchased a number of other PMG products previously, and all have been excellent, high quality products, including this plate. The PMG staff are knowledgeable, and extremely helpful. This plate arrived at my specified destination, as promised, on Saturday, 8/19/17. I highly recommend PMG and their products.
