So I´ve got my Trusmt MB and realized, that I will need some kind of variable height adjustment to have it working on all my lenses on my Ginirig. I found only this http://www.ebay.com/itm/Height-Riser-rail-systems-follow-focus-mattebox-/190353971566 but that one comes from India and due to bad experiences I´d like to avoid to buy from there.

Does anyone know a store which offers something variable? Or how do you deal with the heights of you rigs when it comes to Matteboxes?

Thanks!
