Filter frame EUROLITE Theatre 300/500 Black for theatrical lighting fixtures

EUROLITE Filter Frame Theatre 300/500 Black is a replacement filter holder designed for theatrical and stage lighting fixtures that accept the 300/500 format. The black metal frame secures colour and diffusion filters, allows efficient insertion and removal of gels, and helps protect filters from heat and movement during performances. The frame is compatible with fixtures produced for the 300/500 size standard and is intended for professional and amateur theatre, studio and live event use.

Advantages

The sturdy black metal construction offers reliable support and heat resistance to maintain filter position during long performances. The design enables quick installation and swap of colour or diffusion filters without tools, reducing downtime between cues. A slim profile minimizes obstruction of the light beam while the frame edges hold filters securely to prevent slipping or warping under stage heat.

Suitable for

• Theatrical stage lighting fixtures using 300/500 format filters
• Photography and film studio luminaires sized for 300/500 frames
• Live events and concert lighting where quick filter changes are required
• Theatre and rehearsal spaces that use colour and diffusion gels

Key specifications

• Material: metal frame with heat-resistant finish
• Colour: black
• Compatible filter format: 300/500
• Mounting: slide-in or clip-in style for compatible fixtures (tool-free operation)
• Profile: slim edge to minimize beam obstruction

How to use

Insert the EUROLITE filter frame into the accessory slot or holder of a compatible fixture sized for 300/500 format. Slide the colour or diffusion filter into the frame until it is held firmly by the frame edges. For fixtures with clips, align the frame and press until it locks in place; for slide-in holders, push the frame fully into the slot. To change filters during a performance, remove the frame using the fixture’s release mechanism or by pulling the frame out of the slot and replace the filter as required.

Usage recommendations

Allow filters and the frame to cool before handling after extended use to avoid burns. Verify compatibility with your fixture’s accessory slot and ensure filters used are rated for stage heat. Store spare frames and filters flat to prevent warping and inspect frames periodically for bends or damage that could affect fit.
