Broken window

Hey there, thanks for reaching out! You have either the S380-29 with a 1" shoe or the S385-29 with a 1-3/32" shoe. To determine which series is needed for your window. Look over the dimensions from the diagram below to confirm the depth of your bottom shoe.

Comparison of the S380 and S385 balance shoes.

I am unable to cross-reference the stamp you have, unfortunately, so you'll need to obtain the exact weight of the sash. Once you have the sash weight, you'll be able to use the chart below the product description for the balance you need (one of the two mentioned above) to select the stamp for your window weight.

Since the window weighs 42lbs, you'll need the 2870 stamp. Also the take out clip typically used with these types of balances is part 16-002. Take a look at the measurements to confirm that it will be a fit for your window.

You top sash guide looks like it could be either the 18-008 or the 18-008H. They both have the same measurements, for the most part, but the installation holes are different at the top. The 18-008H has a horizontal slit at the top of the rectangular part of the top sash guide.
