City Theatrical Barndoor for ETC fos/4 Fresnel 5
Details
City Theatrical Barndoors are variable beam shaping devices for wash lights, like Source Four PARS, LED wash fixtures, or fresnels. The soft beam of these fixtures has a wide spread without a defined edge, and this wide beam spread often lands on scenery, backdrops, or areas of the stage where it is not wanted. The large leaves of Barndoors can be adjusted to shutter the light from places where it is not needed.
Barndoors have aluminum leaves for light weight and durability, and nylock nuts to enable the tension of the doors to be adjusted if wear occurs over time. Many have round frames that allow the doors to rotate to the optimum position.
Features:
- Beam control accessory
- For use with various lighting fixtures
- Extra large aluminum leaves for controlling light spill
- Made in the USA

Nice web site easy to navigate. Colorful.
Service was great! Got a response to my question within 24 hours (next business day).
Customer support assisted me with a quest about rated amperage and this being a tax exempt purchase. Very helpful.
