Not sure which item to order. These are 9/16"(1/2"), one is broken but will order both new. Overall length is 28", non-tilt window. Pic shows numbers on the back of existing balancer but they make no sense to me. I'm a former home builder and can replace them myself once I get the new parts. Please advise, thanks much! Steve Hill

Thanks for your photos. Based on what I see here, you have either our Series 380 or Series 385, depending on the depth of the bottom shoe. That's the only difference between them. I recommend measuring your shoe and referring to our dimensions to confirm the best match.
