Description

This 28mm outer straight connector is a core component for building modular industrial structures such as workstations, material racks, and assembly carts. Designed for compatibility with standard 28mm lean tubes, it enables rapid tool-free assembly and reconfiguration of custom frameworks.

  1. ​​Universal Compatibility​​: Fits all 28mm-diameter lean tubes, supporting both aluminum and steel composite pipe systems.
  2. ​​Robust Construction​​: Made from die-cast aluminum alloy (e.g., ADC-12) for high load-bearing capacity and long-term durability .
  3. ​​Corrosion Resistance​​: Anodized surface treatment prevents rust and wear in industrial environments .
  4. ​​Tool-Free Assembly​​: Secures tubes with M6 fasteners using a standard hex key, enabling quick modifications .
  5. ​​Modular Flexibility​​: Enables straight tube connections for rigid frameworks in carts, shelves, and workbenches.
