Window Balance Replacement

Thanks for posting! Both our S380-27 and S385-27 look very close to what you're showing us. The difference between these two balances is the depth measurement of the bottom balance shoe. You will need to measure your bottom shoe. For a 1" shoe depth measurement, go with the Series 380 and for a 1-3/32" measurement, go with the Series 385. Whichever one is chosen, you will use a 2640 option.
