Milestone window balance cap

A home owner from Bradenton says:

My window says it is a milestone single hung series 1000 - w/n 04789. The cap that seems to hold the balance channel in the window broke. The balance channel popped out. Is there a special name for the cap that I can search for to find a replacement piece?

Attached are pictures of the cap missing on one side and the cap in place on the other.

Thank you

Craig

Hello Craig. The cap you are referring to is called a top sash guide. In order for us to properly identify a match for you, we will need to see some photos of it removed from the window. We need to see it from a front and side angle, almost like a "mugshot" if you will. In addition, you will need to also provide to us some measurements and dimensions.

Attached, please find top and side photos of my top sash guide. Please let me know if you need additional photos or measurements to identify my part. Thank you very much.

After I sent a message yesterday, I was poking around your website and found your item number 18-180, which looked a lot like my sag guide. I saw the measurements for item 18-180 and have tried to take the attached pictures to show the comparable measurements to help you try to determine the item I should order. Thank you.

I agree, the 18-180 looks like our best match!
