The Elinchrom Accessory Holder for 21 cm Reflector fits onto the front of the reflector and accepts a complete system of attachable accessories such as grids, filters, diffusers, and barndoors. Their design allows different accessories to be used together. For example: to produce spots of colored light, gels can be used in conjunction with honeycomb grids and then barndoors can be used to avoid flare. The Accessory Holder is repositionable, not rotatable.
