This external clamp base T-connector is designed for 28mm lean tubes, enabling robust T-junction connections in modular framing systems. It utilizes an external clamping mechanism to securely fasten tubes without internal modifications, ideal for constructing industrial trolleys, workstations, and storage racks.

1. ​​Universal Compatibility​​: Fits standard 28mm diameter lean tubes with 0.8–2.0mm wall thickness.
2. ​​External Clamp Design​​: Tool-free assembly via hex wrench; clamps externally to prevent tube deformation.
3. ​​T-Junction Structure​​: Creates stable 90° intersections for rigid frameworks.
4. ​​High Load Capacity​​: Cast aluminum alloy construction supports up to 125kg dynamic loads.
5. ​​Corrosion Resistance​​: Anodized surface treatment for durability in industrial environments.
6. ​​Modular Flexibility​​: Compatible with cross, parallel, and angled connectors for customizable layouts.
