The GFJ-E52 135° straight connector is designed for the Green Frame GF-N modular system with Ø 28 mm tubes, enabling obtuse-angle joints in lean structure assemblies. Weighing 84 g, it integrates seamlessly into configurations requiring an intermediate angular deviation between two straight tubes. The extended version ensures compatibility with 90° connectors within the same system, supporting the design of workstations, racks, and industrial trolleys.
