For most applications, Polyester works best when applied in the working range, ideally at least 50% of the break strength of the strap. At 700 pounds maximum tension, the VT700L is the ideal battery powered tool for a wide range of polyester strapping applications. Operation and batteries are identical to the VT550L. The VT700L is equipped with a high tension motor to increase the tension, and all VT700L tools have a standard heavy duty steel wear plate for heavy duty applications. Competitively priced, the VT700L is a cost effective solution for heavy duty and high tension applications.
