Product information
  • Expander connectors, also called expanding tube connectors or expansion sockets, are available for round tubes with external dimensions from Ø 16 mm to Ø 60.3 mm inclusive, and for wall thicknesses of 1.5 mm to 2.5 mm inclusive
  • Thread sizes M6, M8 and M10
  • Available without nuts or with 1 or 2 nuts
  • Can also be combined with hexagonal screws to DIN933, hexagonal lock nuts (DIN985) and stainless steel hexagonal nuts (DIN985)
  • The action of tightening the nuts (via a screw or threaded rod) expands the connector until it is firmly secured in the tube or box-section profile
  • Allows easy connection of round tubes without having to weld
  • Multiple possible uses such as for tube extension and demountable frames, e.g. for racks and shelving, exhibition stands, cages, aviaries, etc.
