Milgard balancer

Thanks for visiting our website. Your balance closely resembles both our S380-33 and S385-33. The only difference between these two balances is the depth measurement of the bottom balance shoe. The depth of the bottom shoe for the Series 380 is 1" and for the Series 385, it's 1-3/32". You will need to measure the depth of your bottom balance shoe, like in the diagram below, to determine which balance is the most compatible with yours. Whichever one chosen will go with a 3230 option.
