Overview

The BDR-36B is a 4-leaf barndoor sized for KUPO PAR 36 fixtures, giving lighting crews a direct way to trim spill at the fixture face. It uses a 404 mm gel-frame ring with foldable, adjustable blades, so the accessory installs like a color frame while giving more control over where the beam stops.

Why It Matters

PAR cans are simple, durable fixtures, but their spill rarely lands exactly where the designer wants it. A correctly sized barndoor keeps the fixture useful in tighter spaces, especially when the rig has to protect masking, scenery, gallery walls, or camera edges from stray light.

Key Features

• 404 mm ring outside diameter is matched to the KUPO PAR 36 gel-frame opening for a clean accessory fit.
• Four adjustable leaves let crew shape top, bottom, and side spill without changing the lamp, lens, or fixture position.
• Foldable construction packs flatter in the case, which matters when a mixed PAR kit travels with multiple barndoor sizes.
• Black finish keeps the accessory visually quiet on stage and reduces unwanted reflections around the lens opening.

Host Fixture

Designed for KUPO PAR 36. Blade dimensions are A 121 mm, B 169 mm, and C 142 mm, with the wider B and C leaves giving useful control over broad PAR spill. The BDR-PAR family covers PAR 16, 20, 30, 36, 46, 56, and 64, so mixed inventories can be matched fixture by fixture.

Applications

A useful accessory for theatre PAR rigs, club stages, display lighting, rental-house PAR kits, and small studio setups where crew need to contain spill without replacing the fixture.

Compatibility

Fits KUPO PAR 36 gel-frame slots; check the host fixture opening when matching to non-KUPO PAR cans because PAR body dimensions can vary by manufacturer and generation.
