34" Chanel Balance

A quick learner from Califoria says:
Hello. Excellent site. Need to replace whole bunch of my window balances. Like to start out with the first by choosing the right part. Attached are the pictures. Channel Length = 34"; Channel Width = 10/16 and 9/16 as the spring visible side seems wider than the back side, because of rimmed edge. Channel depth = 9/16.

The sash weighs 19 pounds. The dimensions of the [old) top and bottom shoe appears to match the S380-34 series 380. I suspect I need the stamp option 3330 for the weight requirement. Do I have the correct part for replacing the channel balance in the pictures? Many thanks for the help.

Thanks for posting! Before I can offer an applicable replacement for this channel 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?

Hi, thanks for the follow up. Of the two dimensions, my old part shoe depth is 1-3/32". Shoe 15-004. I missed that slight difference in my first post.

Also, I forgot ask, is there a "right" and "left" channel balance? You only asked about the bottom shoe, are there different styles for the top shoe as well? Many thanks.

Thank you! In that case, I recommend the S385-34 channel balance with a 3330 stamp option. Does that look about right? Make sure to compare your sash weight to the weight range shown for the 3330!

There are no left or right hand balances, they are all non-handed. As for the top attachment, there aren't many variations and they're pretty easy to spot. However the bottom shoes are a bit trickier; there are a few more variations, and the differences between them are very subtle.
