  • Fast, time saving installation from only one side
  • For SHS and other hollow sections
  • No need to weld, no hot work permits
  • High resistance to shear and tension
  • Independently approved product performance

technical line drawing of Lindapter Hollo-Bolt


1Safe working loads shown are based on use in S275 structural hollow section and use 5:1 factor of safety. The safe working loads, in both tension and shear, are applicable to the Hollo-Bolt only. Failure of the section, particularly on those with thin walls and a wide chord face, could occur at a lower figure and strength of the section should be checked by a qualified structural engineer.
