Want to insure I order the correct parts!

Question

Attached are photos of the channel balance used in my tilt window. Note the marking is 3520 BSI VN. My balances come with hooks attached to the cord. The balance length is 36", width is 9/16" and the depth is 5/8". I believe that the correct Swisco replacement part is S770-36 Option B. Is this correct? Does the S770-36 come with hooks attached to the cord? The photo on the Swisco website appears to show that a block attached to the cord.

Thanks for any guidance you can provide.

Thanks for posting. I agree that our Series 770 is a good option for the base channel, but the clip at the end of the cord is different. We will have to specially make an S770-36 with a 62-105 hook at the end of the cord. Does that look good to you?

If so, please let me know how many you need and I'll email you a special order link and price quote.

You may want to also confirm your exact sash weight. We'd be going with our 36B stamp for sashes weighing 16 through 22 pounds.
