Footage Chain Note: Bulk chain is priced per inch. All chains are sold by the inch unless a 10 foot minimum is noted. Spooled chains sometimes have spliced lengths from the factory so we cannot guarantee continuous lengths of any specific measure. Cut chain shorter than 12 inches cannot be returned.
