If possible I need someone to get back with me quickly. I'm in the process of selling my house and I need to fix a couple windows. I know it will take some time to get the items ordered and sent to me I would appreciate any additional assistance. Thanks, Glenna

Hey Gienna. Are the coil springs 1/2" thick? If so, then these are Series 160 Coil Springs. A spring stamped 5.5 should be replaced with the S160-5 spring, which supports 5.5 lbs of weight apiece. The pivot shoe that uses these springs is often our 15-111, but compare to confirm. Let me know if you have further questions.
