This Chimera Quick Release Speed Ring is circular, and constructed of heat resistant aluminum. It allows mounting of a Chimera, or almost any other brand rectangular video-series softbox to your light fixture. It fits any tungsten, HMI or CDM fixture that accepts a 6½" accessory.
The Quick Release System releases the tension of the wands in the frame of your softbox, allowing it to collapse easily for breakdown, or for moving on quickly to the next setup without disassembling the box.
