Looking for a rail clamp larger than Arca Swiss compatible

  1. I'm looking for a clamp for a rail that is wider than the usual 37-38mm Arca Swiss rail/plate; specifically this rail at its widest is 46mm. The profile of the rail is the typical isosceles trapezoid with slightly different side angles than AS - there is some wiggle room here.

    I've found some video or astrophotography clamps whose jaws open wider but either the angle of the jaws is too disparate to effectively grip this rail or the jaw opening is so wide they won't clamp the rail even when closed.

    Any suggestions for sources?
