Window balancer
Hello,
With this combination of attachments and 1" shoe depth, you could have the S380 channel balance. You'll also need 2630 (27") and 2730 (28") spring strength options for your replacement balances. Thank you and let us know if you have any other questions or concerns.
Your photos show the S380-27 (2630), as well as the S380-28 (2730) channel balances. If you click on the highlighted product codes, you'll be brought directly to our product pages where you can add these items to your cart. If you'd prefer, you're also welcome to give our customer service team a call at (888) 991-1929 to order over the phone.
