103" Breaking Crank with Spline DIM=94x7x5 100% Waterproof & Weatherproof –103" Breaking Crank with Spline. This crank has a splined U Joint that attaches to a splined roll tube with included snapper pin. This is a breaking crank style, so the crank handle assembly can be folded out of the way from the tailgate or other obstructions. This also helps with longer crank handles so they don't touch the ground when stored.
