Window balance

Thanks for reaching out! Your channel balance resembles our Series 350 non-tilt window balance. To determine which of these balances is the correct one for your window, you'll need to confirm the length of the metal channel.

Once you've selected the channel length from the list of Series 350 balances, you'll need to select the stamp option before you check out from your online cart. There should be a stamp on the metal channel. 

If there is no stamp or if you are unable to cross-reference it, you'll need to obtain the exact weight of the window and chose your stamp from the weight ranges on the list. You'll find the chart below the product description of the balance.
