High-Performance Beam Control for Large Fresnel Optics

The ARRI 4-Leaf Barndoor True Blue (344 mm / 13.5", L2.40950.0) offers professional beam-shaping precision for large-aperture optical attachments. Built with four large, movable metal leaves, it allows cinematographers, gaffers, and studio lighting directors to cleanly shape the light beam, control edge falloff, and eliminate unwanted light spill across the set.

Direct Fresnel 15–65° Optic Mount

Engineered for seamless integration within the ARRI ecosystem, this 344 mm barndoor slides directly into the front accessory slot of the ARRI Orbiter Fresnel Lens 15–65° Optic. It is also fully compatible with ARRI's classic True Blue lighting fixtures that share the standard 344 mm accessory ring size, making it a versatile tool across mixed lighting packages.

Heavy-Duty Cinema Build

Manufactured to ARRI's strict broadcast standards, the L2.40950.0 features heat-resistant metal components that ensure long-lasting performance on high-wattage fixtures. Smooth-action friction hinges ensure each leaf adjusts easily with gloves on and maintains its physical position throughout long production days.
