Alcan window balances & top sash guides

Quick Learner from Bradenton, Florida
I wish to purchase replacement balances and top sash guides for my Alcan non-tilt windows installed late 1980s. See pictures included. I need help identifying proper replacement parts. Alcan numbers on existing balances are: 1710W, 1710E, 2910W 30", and 2930W (all 1/2").

I'm guessing Product Code: 18-161 for the sash guides and Series 380 or 385 for the balances?

Thanks,

Juan

Thanks for posting, Juan! You're right, that does look like our 18-161. Do the dimensions match?

As for the balance, I just need to know a bit more information about the bottom attachment. Please take a look at our 15-004 and 15-005 channel balance shoes, and note their depths. As you can see, they are 1-3/32" deep and 1" deep, respectively. Which one more closely matches your own bottom attachment?

The dimensions match on the top sash guides (18-161). My existing shoe depth matches the 15-005 shoe more closely (mine are a hair under 1"). So which balances will work best? Series 380?

Thanks again, Juan

Hey, Juan, thanks for getting back to us. I agree, the Series 380 looks like it'd be the best match!
