Norandex window balance

A handy person from Ormond Beach, FL says:
we just ordered a plastic sash guide for our norandex window. It was the guide screwed into the removable window. Got that replaced, but see the pulley on the balance channel is broken too.

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

Thanks for posting! The stamp is not actually an identification number. All it really does is tell you what the strength of your balances are. That's important, of course, but it won't tell you what the attachments are. Our balances are determined by a few different factors.

Take a look at our Channel Balance Home Page and follow the steps shown in order to find what Series you have. Let me know what you come up with!
A quick learner from Florida says:
We went through the channel balance home page and it looks like we need the series 380 or 385, as ours has the wings on top and shoe, but both look the same.
Can you help us with that, if so, do we need the whole channel or the pulley?
Thank you

Did you see the bottom shoes for both Series 385 and Series 380 balances? They are the 15-004 and 15-005, respectively. Compare the dimensions we show to your own shoe in order to determine which is a closer match.

They pulleys cannot be replaced, so you will need the whole balance.

Thank you for all your responses.
We will order.

We just ordered two, as was recommended, of the series 380 channel balance.
It was the left side that broke. After taking the window out, the left fell out, but the right side is all the way at the top.
My question is how do I get it down to replace the new one ordered also?
Then do I install the right side, then left. The video shows one side being replaced?
Thanks again,
Vern

Hey, Vern. Did the right side shoot up only after you removed the window sash, or was it like that to begin with? If it shot up after you took the window sash out, then you probably didn't pop the take-out clip to catch it. You'll have to force the balance down, hold it steady while you pop the take-out clip, and then ease it into place under the clip. It will take some elbow grease, so having a friend on hand to help out wouldn't be a bad idea.

As long as both take-out clips are extended, replacing two balances at once shouldn't be a problem. Our video only shows one side being replaced, but you can do both sides the same way without any problem.
