JBF National plastic crank handles are designed for weight reduction without sacrificing strength and durability. The plastic construction reduces the overall percentage of corrosive surface areas ensuring maximum longevity. For increased safety, this model comes with a phenolic revolving handle to ensure maximum grip. For added customization, we offer these crank handles (also known as crank arms) with a blind pilot hole to accommodate custom bore sizes. Please see component diagram below.
