These models are semi-automatic sealless steel strapping tools where the strap is tensioned pneumatically and sealed manually.

Advantages:
  • easy use for strapping of flat packaging goods
  • pneumatic drives allow fast and strong tensioning
  • equal tensioning of steel strapping is possible thanks to pneumatic drives
  • as this tool works sealless, total strapping costs can be reduced by ~ 10%
  • no suspension necessary due to its light weight
