Broken Block and Tackle

Question

We recently moved into a new house and the windows are original from when the house was built in the late 80s. They are in good condition, but the two master bedroom windows need new block and tackle mechanisms. They are missing in one window and the two others are broken in the other. I uploaded photos of the end and they are
27 inch metal stamped with "2690K". I am somewhat handy and hope that if I can confirm the correct replacement part that I can repair them. Thanks.

Hello,

I can't be sure but it looks like the top fitting of your balance may have wings. If so, take a look at the S395-27 channel balance.

Since your 2690 stamp is from an outdated weight system, you'll need to weigh your sash to determine which strength option you'll need. There is a chart on the product page that explains how to choose your option based on the sash weight. Thanks for posting!
