Filter frame EUROLITE 235 x 235 mm black

The EUROLITE 235 x 235 mm black filter frame is a metal accessory designed to hold square lighting and color filters sized 235 x 235 mm. It provides a rigid support for gel sheets and other filter materials, enabling secure placement in stage, studio and photographic fixtures. The black finish reduces stray reflections and helps maintain consistent light direction while the frame's construction allows for easy insertion and removal of filters during setup changes.

Advantages

The black metal construction offers durability and resistance to heat generated by lighting instruments. The frame's precise dimensions keep filters flat and properly aligned, preventing light leaks at the edges. Its simple design makes swapping filters quick and reliable, and the neutral black color minimizes visual distractions when installed in lighting fixtures.

Suitable for

• Theatrical lighting fixtures and lanterns

How to use

Slide a 235 x 235 mm filter sheet into the frame opening, ensuring the filter lies flat against the inner edges and is fully seated. Insert the assembled frame into the lighting fixture's filter slot or holder, aligning it so there are no gaps between the frame and the fixture to avoid light leakage. To change filters, pull the frame out, remove the existing filter, replace it with a new sheet, and reinsert the frame. Handle the filter material at the edges to avoid fingerprints on the usable area.

Usage recommendations

Inspect the filter frame periodically for bends or warping and keep the frame clean and free of debris. Use filters rated for the fixture's heat output and avoid exposing plastic or low‑temperature materials to high-intensity lamps. Store frames and filters flat in a dry environment to maintain shape and performance.
