The KUPO ETI-W24 is a 24-leaf manual iris shutter designed to move from open to fully closed. It belongs to the ETI iris family, but its full-close action makes it the choice when the lighting setup needs aperture control that can also shut the beam down completely.
Why It Matters
A standard iris is often used to resize a beam, while an iris shutter can support cueing and masking needs where full close matters. ETI-W24 gives technicians a 24-leaf option with heat-resistant construction and the larger ETI body dimensions listed in the specification.

Frequently Asked Questions
How is this different from a normal iris?
ETI-W24 is described as an iris shutter that moves from open to fully closed, so it can support full-close cueing or masking.
Does it use the same body size as ETI-F18 and ETI-F24°
The specification lists the same A 120 mm, B 137 mm, C 13 mm, and D 102 mm dimensions.
Should I assume it fits every profile fixture?
No. Because the specification does not list a specific fixture family, host fit should be matched before specification.
