This doesn’t get much press, but if you are having a problem mounting a camera around your tennis court, or some other special situation such as a very wide rail on the fence, we can modify the QM-1 to fit.  In this particual situation, here is a picture of an adjustable QM-1 I made for a soccer coach in England:

This QM-1 was modified to adjust from 2 1/4 inch to  3 and 3/4 inch.

Let us know what your needs are, and we can probably come up with a solution!
