Hi, my name is Ean, and I am a general contractor.
I have a client whos has 3 vinyl windows that all of the Block and tackle has failed and is wanting them replaced.
I am trying to find the proper replacement parts and purchase the 6 that I need.
Any help is appreciated.
Thank you,
Ean

Hello, With this combination of attachments, you could have either an S380-29 or S385-29 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 2840 spring strength options for your replacement balances. Thank you and let us know if you have any other questions or concerns. Comparison of the S380 and S385 balance shoes.
