We need to replace about 16 block and tackle type window springs. The pictures show the ends and the spring mechanism. The metal shaft is 29 inches long. Do you still have this type of spring

Thanks for posting. Sure, we should be able to help. See our S390-29 channel balance to start out and let me know if this would be a good match.
