Heavy lifting window

I have a heavy lifting window and saw some parts are broken.

The first photo shows the part where the window itself sits and looks kind of bad.

The 2nd one, shows like a little arm that is missing from one side of the window. The one it has it looks like metal not plastic.

Any advice?

Thank you

Your pivot shoe looks like our 15-129 and the tilt bar looks like our 26-021. You say you have a heavy window, though. Is it hard opening and closing the sash? If so, you might need a new window balance. I think you have something like our Series 770 but check it out and see what you think.

Do you have the screws that goes with 26-021? or does this part comes with it? Thanks

The 26-021 doesn't come with screws, but you can either re-use your old ones or use our 33-055.
