Failed Balance in a Single Hung Window

Home Owner from Seattle
A plastic piece broke on the left side of the window. You can see it placed close to a similar piece on the right side. What is this piece? I would like to replace it to repair this window.
Thanks, Adrienne

The broken piece you show there is the bottom nylon fitting on your channel balance assembly. If that broke, then the rest of your balance may not be far behind. I recommend watching the two videos below to get a better idea of what you're working with. Then, show me some photos of your assembly, as outlined by our videos, and I can recommend a replacement.

Okay, here are the details that will help you identify the parts that we need. The # photo didn't get uploaded, but it is B.S.I. 0940 and it's 10"
Thanks, Adrienne

Thank you! This information is a huge help. Looks like you need a new balance entirely. In addition to the nylon fitting breaking off, it seems the block and tackle system has also come undone.

We can supply this balance to you but it will have to be a custom order due to its extra small size. With that in mind, can you just tell me how many you needed? Once I have a quantity, I can email you a purchase link and price quote for that quantity. Please note that our minimum for these is 2.

You got it, I'll send that out to you now.

Just one last thing that I neglected to explain beforehand: the nylon fittings we'll be using to construct this balance will be the 19-002 top and 15-001 bottom. I believe these will match yours, but take note that the 15-001 is 1-1/8" deep. We also carry the 15-002, which is only 1" deep. If you need the 15-002 instead, let me know and I would be more than happy to change it for you. The image below will show you what I mean.
