Accessory Holders screw to the side of the fixture and allow the user to insert a range of other accessories. Accessory Holders provide a secure mounting platform, prevent accessories from falling out if the unit is tipped or hung upside down, and block any stray spill light from the fixture. Accessory Holders are required for mounting any additional accessories to ColorBlaze or ColorBlast fixtures. Accessory holders can accommodate an assembly of accessories (i.e. lens and top hat). Accessory Holders are not required for ColorBurst fixtures.
