Manual steel strapping tools are the simplest and most basic method of tensioning, sealing and cutting steel strapping. Polychem offers a variety of manual tools to suit your budget and needs. Depending upon your application one can either invest in a three tool system (tensioner, sealer and cutter) or a combination sealess tool that will perform all three operations without the cost of seals. 3/8''-1-1/4'' x .031 RD and HT strap size.
