Unique 29-b-20. The length of the metal only channel is 30" I need 8 balancers. Possibly with the end pieces already revived onto the channels. santiago

Hello, thank you for posting, It appears you have either our Series 351, with a 15-002 bottom attachment, or Series 390, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need. You will need a 30" balance with a 2920 stamp option. Please review and let us know if you have any additional questions. Comparison of the S351 and S390 balance shoes.
