Window channel balance

One of my window channel balances has a broken plastic pulley wheel. Stamped on the opposite side of the opening to the spring channel is 27-3. The other one the nylon string where it attaches to the clip is frayed. So I need one for each side please.

With a broken pulley wheel, you will definitely need to replace the balance. It sounds like you have a 28" block & tackle balance with a stamp option of 2730. I'm afraid that's all I can tell based on your information, though. Now you just need to pick out the top and bottom fittings in order to determine the Series.
I recommend that you look at our Channel Balance Home Page and follow the steps in order to find the Series that best matches what you have.
