Balance for windows

Hey there!

It looks like you need either the Series 380 or Series 385 channel balance, depending on the depth of the bottom fitting. You'll have to measure as shown below to determine which Series is best for your repair.

For the balance stamped 29 3, you'll need to select the 2930 option.

For the balance stamped 30 3, you'll need to select the 3030 option.
