Replacement part for windows

Question

Hello -

We are trying to find this part to replace in our windows. It looks like it would be the 350 or 351 25" 2420, but want to be sure before I order a bunch of them. Thank you!

Thanks for your photos. Based on what I see here, you have either our S351-25 or S390-25, depending on the depth of the bottom shoe. That's the only difference between them. I recommend measuring your shoe and referring to our dimensions to confirm the best match.

Comparison of the S351 and S390 balance shoes.
