City Theatrical 7 1/2in. to 6 1/4in. Adapter
This adapter will extend the use of your accessory inventory by allowing larger accessories with a 7 ½” frame size to be used in a standard Source Four with a 6 ¼” frame. You could use older top hats, or even newer Source Four PAR size top hats, color scrollers, and effects devices. This can extend the use of your stock, and save you money.
