<p>What are the differences between the Profoto Speed Ring 100660 vs Profoto RFI Speed Ring 100501? They both are compatible with a Profoto RFI 1 x 4 Strip Box.</p>

<p>If you have a RFI modifier just get the less expensive RFI speed-ring. It is color coded to make assembly a little easier. </p>

<p>Marc, Profoto got back to me after I had asked this question here. The Profoto Speed Ring 100660 is only compatible with their RF and a couple of their OCTA boxes. Profoto RFI Speed Ring 100501 is only compatible with their RFI soft and strip boxes. Thanks for your assistance.</p>
