The Fromm P326 comes with numerous advantages over other battery tools for poly strapping. The P326 has a new reinforced single 18 volt motor that operates the tension and sealing process, which reduces its overall weight to 8.7 pounds. The power supply battery is a Li-Ion 18 volt battery that allows up to 600 strap cycles per battery charge. Its simple one hand operation makes the process quick, simple, and uses less man power than traditional hand tools. The adjustable tension speed of the P326 allows the operator to choose the tension force based on individual applications. The average seal strength is up to 75% (depending on strap quality). The Fromm P326 comes with 2 batteries and a charger. When you purchase this tool please leave a note of what size strapping you currently want the tool set for.
