Balancer and Top Sash Guide

Thanks for posting! Your balances look like they are either the S380-25 or the S385-25 with a 2440 stamp. The length of the balance is based on the length of only the metal channel. So, be sure to double check the channel length.

To determine the series needed for your balance replacement, you'll need to confirm the depth of your bottom shoe. It should either be 1" or 1-3/32".

In regard to the top sash guide, because yours has a slit in the top, I recommend part 18-008H. Again, look over the dimensions to confirm that this is the right replacement.
