Rosco manufactures gobos holders for use in some of the most popular lighting fixtures. However, given the incredibly wide range of fixtures available around the world, there are many instances where Rosco does not have a holder available. In that instance, you should contact the manufacturer of the specific fixture for their recommendations. Consult the fixture specifications page to determine what size gobo is required for your luminaire and whether one of Rosco's gobo holders will work.
