Channel Balance

Hello, thank you for posting,

It appears you have either the 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 measure and determine which balance you'll need. 

You will need a 28" balance with a 2730 stamp option. Please review and let us know if you have any additional questions!
