Replacement 3435 balances

With this combination of attachments, you could have either the S380-35 or S385-35 channel balance. You’ll need to measure as shown below. The Series 380 has a 1" bottom attachment, and the Series 385 has a 1-3/32" attachment. 

You'll also need to weigh your sash to determine which option you'll need. There is a chart on the product page that explains how to choose your option based on the sash weight. Thank you and let us know if you have any other questions or concerns.

We actually offer the 7/8" deep 15-029 bottom fitting shown below, which we can supply attached to your replacement balances through a custom order. First, we'll need you to confirm the weight of your window sash to determine the correct strength option for your replacement balances. Thank you.

One of our customer service representatives passed along that your window sash weighs 20-1/2 pounds. We just sent over an order link and price quote for you to review. Take a look and let us know if you need anything else.
