It is a 1/2" X 35" with a number of 3440BSI on the metal part. We can't find that number in your product list. Can you tell us if it goes by a different number? The window is 10 years old.
Ordered item #18-161 sash guide on 4/16, replaced, but see that the pulley is broken too.
The number on the metal channel is #3440 BSI, but we don't see that number in the product list. The channel is 35"x 1/2".
Enclosed is a picture of the pulley. Do we need just the pulley or the whole channel balance?
Thank you
Vern
