Product Description
Overview
The KUPO ETF-CF304 is a color frame for S4 5°. It gives the fixture a properly sized front accessory holder for gel, diffusion, or compatible color media so the beam can be colored cleanly without loose sheets or improvised clips.
Why It Matters
A color frame is simple, but the fit has to be right. ETF-CF304 keeps prepared gel media centered at the fixture face, which helps crews label colors, change looks quickly, and avoid disturbing focus during service or show turnaround. The 5° lens tube is a very narrow long-throw setup, so the frame choice should be treated as a specific accessory match.
