Pre-Cut SALE! MGP Furler 50, 3/8" (10mm), Black/Grey, 71 FeetContinuous line furlers are harder on the furling line due to the high speed at which they turn and the jaws of the furler drive unit which grip the rope like the jaws in a self tailing winch. Traditional core dependent ropes can't be spliced end for end without an increase in diameter, which would catch in the furlers' jaws. MGP Furler 50 from Marlow is a structural cover over a nonstructural core. The cover is made from a Vectran Technora cover
