IWC channel balance 32C BSI

I have a "Single Hung window" by IWC (apparently they don't make my windows anymore). Double-paned and tilt.

I need the balance channel (pictured above). It measures at 32" long, 1/2" wide, 1/2 deep.

In the last picture one can see 32C B.S.I stamped on the channel.

Thank you!

Hello,

Your balance looks like a match to our S770-32  with a 32C spring strength option. Carefully compare the measurements of your pivot shoe and pivot bar to our 15-154 and 26-369, Please let us know how and if they differ at all and we will continue researching for you. Thanks for posting!

Thank you! Yes as best as I can tell, the measurements match. (My original cam is white not blue which I imagine is of no relevance). Can I ask what is your return policy just in case I do order the wrong part?

You are correct that the cam color does not determine compatibility. As long as all of the dimensions line up, you should be good to go. Also, you can review our return policy here. Please let us know if you have any other questions!
