The SF1250 Tensioner Tool is a heavy duty ratchet banding tool that winds the banding around a slotted windlass shaft to develop tension. Designed for stainless steel, this tool is fast, reliable and features a cutter to cut the strap once the band has been tensioned. This tool also features a hammer knob which allows you to hammer down and close the tabs of the buckle once the tensioning has been completed. This SF1250 is popular for sign mounting, insulation work and other general banding applications.
