The New Standard in Thread Wrap. In development for over a year and rigorously tested by rod builders, ProWrap™ thread is available in 80 colours in both Nylon and Colour Fast – in three familiar spool sizes – 100yd, 1oz. and 4oz. The 100yd snap spools work perfectly on power wrappers. ProWrap™ thread features strong tensile strength and bright colours that have been pressure dyed for colour consistency.
