Kupo 4ft Square Tube Male for Butterfly Frame

The Kupo BF45 is a 4ft (1.2m) male connector tube for building a butterfly frame, made from heavy-duty black anodized aluminum in a 30x30mm square-tube profile. It pairs with a matching female tube and uses a quick-release, spring-pin mechanism for fast, tool-free assembly and disassembly. It's a durable component for building custom-sized diffusion or silk frames on set.
