channel balance

Question

I have older windows built earlier than 1940s and I would like to know if I should get the 351 series or the 390 series.

There is marking 2620.

Please advise. Thank you.

Hi there!

I agree that your balance looks like a match for the Series 351 or Series 390, but you will have to measure the bottom shoe as shown below to determine the best pick. You can also select the 2620 stamp option for the 27" replacement balances.
