Both models are handy light weight tensioning and sealing tools to strap flat packages (i.e. pallets, bales, crates und various packages) using plastic strap- ping and metals seals. Reliable, robust and service-friendly tools also suit- able for non-stationary applications. Thanks to the windless tensioning system very high strap tension can be achieved. Special serrated seals and the pa- tented sealing force balance system guarantee a very high seal joint efficiency. The seal joint is made in no time by operating the sealing handle until it hits the stop. A separate handle, consisting of a grip ball and a bolt are available as option for horizontal applications.
