CWS Window Channel Balancer

Question

Hello,

Trying to identify a channel balancer. It's non-tilt window, 1/2" channel, 24" long. I weighed the window and it's 30 lbs. The window is made by CWS and is double pane. I know the clips are identical (shape and size) as S385 (I know because this window I had replaced while other windows in the house are original and I'll be ordering S385 for those as they have the slightly smaller plastic piece on one end but otherwise identical.)
The only marking on the metal rail is "23 98S1". The other rail has the same marking. I know this number is usually used to determine the proper weight. If I'm correct about this being S385, then I think I would need S385 2365 (for 30-34 lbs).
I'm ordering a bunch of the S380's for other windows of various sizes/weights.

Thanks!
Mike

Hey Mike. If you're absolutely certain the nylon fittings match those used on the Series 385, and if the metal channel length is 24", not including those fittings on either end, then yes the S385-24 with a stamp option of 2365 sounds right. If the window weighs exactly 30 pounds, that stamp will cover that exact weight (30 through 34 pounds). Let me know if you have further inquiries.
