23 4 JS CALDWELL Window balances

Hello there!

Depending on the depth of your balance's bottom shoe, see our S351-24 or S390-24. You'll notice the Series 351 comes attached with a 1" deep shoe, while the Series 390 comes attached with a 1-1/8" deep shoe. Take a look at the diagram below to determine the best match. You'll also need the 2340 strength option for your replacements.
