Overview
The Kupo BF45 4” Square Tube Male is a professional aluminium frame component designed for use within Kupo’s modular butterfly frame system. It is used to build or extend lightweight yet durable frame structures for mounting diffusion, silks, nets, or blackout fabrics in film, television, and photographic lighting setups.
Manufactured from black anodised 30 × 30 mm aluminium alloy, this 1.2 m male tube section connects with a matching female BF40 tube to form complete butterfly frame assemblies. The quick-release spring pin system allows for fast, tool-free assembly and breakdown, making it ideal for fast-paced production environments.
This component is designed for flexibility, allowing crews to build multiple frame sizes depending on production requirements, from small rigging setups to large overhead diffusion systems.
