Window part

Thanks for posting! The part you have circled in red is the top sash guide. To identify it, I'll need to see a front facing view and a side profile view. Take a look at the video tutorial below for instructions on how to remove and install this guide.

Hi Bhavini,

While that might help to narrow down the options, unfortunately I cannot use that to determine the exact replacement you need. I'll need to see the photos of the part to identify it, when you are able to do so.

I do apologize that this isn't an easier process.

Thanks for the photos. Your top sash guide reminds me of the 18-166 5/8" Top Sash Guide. To confirm that this is the right replacement, carefully look over the dimensions and compare them to your existing guide.
