Made from an advanced polyethylene terephthalate (PET) material with a helical profile, SPIRA-FLEX significantly reduces frictional resistance and minimises snagging. The super flexible 4mm Ø SPIRA-FLEX draw tape is a significant improvement on standard nylon and steel draw tapes. The innovative helical profile and advanced PET material significantly reduces friction, kinking and coiling allowing for longer smoother runs.
