This 28mm Aluminum Alloy Lean Tube Inner 90° Connector is designed for internal corner connections in modular assembly systems. Crafted from lightweight yet durable aluminum alloy, it enables quick construction of rigid 90° angles within lean manufacturing setups such as workbenches, flow racks, and material handling carts. Its inner-type design ensures seamless integration with standard 28mm tubes while maintaining structural integrity under load.

1. ​​Precision Angle​​: 90° internal bend for compact corner joints in confined spaces.
2. ​​High-Strength Material​​: Aluminum alloy construction offers corrosion resistance and a 30% weight reduction versus steel equivalents.
3. ​​Tool-Free Assembly​​: Compatible with standard M6 hex keys for rapid installation/disassembly.
4. ​​Universal Compatibility​​: Fits all 28mm lean tubes (0.8–1.2mm thickness) without adapters.
5. ​​Reusable Design​​: Enables reconfiguration of layouts for dynamic production environments.
6. ​​Smooth Finish​​: Anodized surface minimizes friction during tube insertion and resists scratches.
