Channel balance for 1993 Skyline mobile home

A quick learner from Lyle, WA says:
I have a 1993 Skyline mobile home with a broken 23" channel balance. The top guide looks like 19-005 though there is a groove that I don't see in your photos. The bottom guide is 15-005. The markings are "22 4 CALDWELL JL." The windows weights 21lbs. Can you direct me to the correct option. Is 2210 is for a 21 lb window?

Thanks for posting! It sounds like you have a S380-23 channel balance. Does that look about right? Based on your stamp and sash weight, I'd also recommend the 2240 stamp option. It can support a window sash weight of 19 through 23 pounds.

Please keep in mind that the weight range information is based on 2 balances per sash. Balances are designed assuming friction in the jamb weather-strip will carry a portion of the sash weight. Suggested sash weights are approximate.
