Try the DX Engineering Saddle Clamps as they have a lot of contact area
with the mast with the cast aluminum saddle. The 2" size comes in two
bolt diameters, obviously the 3/8" u-bolt can handle more tightening torque.
We used three for boom plate to mast clamping of two 40m Moxons, so far
so good w/o any pinning.
