Channel balance is stamped 1610F

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 17" balance with a 1610 stamp option.

For the top sash guide, please start by comparing the style and dimensions of the 18-009, 18-064 or 18-166 to see how they match up to your original. 

Let us know what you think!

No problem! Please let us know if you have any future hardware questions.
