Good Afternoon,
I am looking to order multiple sets of window balances. They have a stamp 2730 is all I can make out on it. It's 5/8" diameter, but I can't figure out what series it is?

I am guessing I need 2 per window, and need to replace them all on 4 windows.


Correction: It's a channel balance NOT a Tube Balance. Its 1/2" Wide Channel Balance.

It's one of these at the link, but the only engraved stamp I can find is 2730 BS


The metal portion is 28" long
This is a NON tilt window

It looks barely wider than 1/2"
Top fitting does NOT have wings
Bottom fitting DOES have wings
Depth of bottom fitting 1"

Hey there,

Thanks for reaching out! Your channel balances appear to be the Series 350 Channel Balance assembled with a wingless top guide and a winged bottom shoe. Although, I would be sure to double check the depth of the bottom shoe. The shoe that comes assembled on this balance has a 1-3/32" shoe depth. 

If your shoe is truly 1", please let me know as this will need to be a custom assembly. I would also need to know the exact number of balances you intend to purchase; there's an order minimum of (2) per custom balance.
