The Double Hole Function Accessory is a versatile connector designed for 28mm lean tube systems, enabling flexible and customizable assembly in industrial setups. It serves as a pivotal component for creating cross-angled structures, expanding frameworks, or adding auxiliary fixtures like tool holders, signage, or guides to workstations, carts, and storage racks.

1. ​​Dual M6 Mounting Holes​​: Standard 25mm spacing for attaching functional add-ons (e.g., wheels, hooks, panels).
2. ​​Horizontal Alignment​​: Secures flush to tube surfaces for stable, level installations.
3. ​​Angle-Free Assembly​​: Combines with identical units to form rigid intersections at any angle.
4. ​​Heavy-Duty Material​​: Cast aluminum alloy (ADC-12) for corrosion resistance and structural integrity.
5. ​​Tool-Free Compatibility​​: Works with standard 28mm lean tubes via clamp-on or bolt-on methods.
6. ​​Reusable Design​​: Enables rapid reconfiguration of production lines or logistics systems.
