#4.5 Zippers

Veterans of zipper repairs have probably seen their fair share of #5 metal zippers, particularly on men’s pants. They may have also encountered #4 zippers, perhaps on pouches or handbags. #4.5 zippers fall in between size #4 and size #5. Since the #5 size is a medium-weight zipper for jackets and jeans, the #4.5 size can be thought of as somewhat light weight size. #4.5 zippers can be found on women’s pants and other applications that require a lighter-weight zipper.
