Window Master

A landlord from Spring Valley CA says:
I have 25-30 year old Window Master, single hung, single glazed windows. I think I want the 380 series balance. The stamp on the side is- 23 2 cu cmc2. I hope the pictures help. The channel measures slightly over 1/2" and the bottom piece of plastic is 1" deep just like the description. It's 24" (metal only or channel without ends). The S380-24 is the one I'm looking for but don't understand the option such as 2310-2350 add .$75. What's that. Please advise if I am close.
Thanks Keith

I agree, the S380-24 looks like a good match. As for the stamp options, these indicate the strength of your balance. Based on your stamp of 23 2, I would recommend our 2320 option.
