Vocas 0250-0196 114 mm Flexible Donut Ring Matte Box Accessory

The Vocas 0250-0196 114 mm Flexible Donut Ring is a matte box accessory that closes the opening between a lens and a rail-mounted matte box. Designed for matte boxes with a 114 mm clamp diameter, it accommodates lenses approximately 2.8" to 3.9" in outer diameter while helping limit stray light and dust.

Built for 15 mm rail camera setups, the soft, flexible ring adapts around different compatible lens diameters while maintaining the matte box seal. It suits cinematographers and camera assistants who need a flexible donut ring for matte boxes, a lens-to-matte-box light seal, or a 114 mm matte box accessory for professional camera builds. Its pliable construction also supports efficient lens changes during production.

Vocas specifies compatibility with any matte box featuring a 114 mm clamp diameter and lists the ring with the MB-260 Compact Mattebox, MB-256 Matte Box, MB-216 Matte Box, and related 15 mm LW kits. Manufacturer item code 0250-0196 and EAN 8720041024040 identify the component, which weighs approximately 0.2 lb.
