Balancer and Top Sash Guide

Question

Hello,

Looking for the balancer and top sash guide for a vinyl window. I attached the label of the window. Seems like the top sash guide is your part number 18-008. The balancer is 26" long. It has the number 2440 BSI KM embossed on it. Please see attached photos. Thank you for your help.

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.
