ParaZip 415/215 Barndoors (Set of 2)
Manufacturer: Kino Flo
Product Code: BRD-Z42
Barndoors are available but rarely used. The most effective ones are the doors along the longer edge of the fixture. On this axis the doors actually have some effect. The side doors have little effect due to the deep set parabolic reflector.
The ParaZip barndoors (BRD-Z42) are sold in sets of two and can be individually mounted. The Barndoor hinges can be tightened with a screwdriver if they become loose over time.
