#8 Molded Plastic Heavy Duty Separating (Jacket) Zipper

#8 molded plastic separating zippers feature teeth that measure approximately 8mm (0.3 inches) wide when zipped. Often called sport zippers or parka zippers, #8 molded plastic separating zippers separate at the bottom, jacket-style. These are one-way zippers (they have one slider). 

This is a heavy-duty zipper that is the perfect in-between size when a #5 gauge is too light, but a #10 is too heavy.
