Need a pair of window balancer kit

Hello, thank you for posting,

With this combination of attachments, you could have either an S380 or S385 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. 

Are you able to confirm the length of the metal channel excluding the nylon attachments? We will also need to know the number stamped on the metal channel. If there are no visible numbers, we will need the weight of the window sash to determine the correct strength to support the window sash.
