Hey there,

Thanks for reaching out! The balances you have appear similar to our S380-29 but with a 15-029 Winged Balance Shoe. Which will need to be a custom made assembly. Since your balance is stamped with a 28D, I believe you'll need the 2840 stamp for a sash weighing 23 to 28lbs.

I am happy to get the order link made up for these balances but I'd just like to confirm that all (14) balances you need have the same stamp.

In regard to the plastic "cap" at the top of the sash, this is the top sash guide. This part helps to prevent the balance from shooting into the window frame and guide the balance as the window opens and closes. Yours appears to be the 18-180 1/2" Top Sash Guide.

To confirm if this is the right replacement, carefully review and compare the dimensions below.
