two sides of channel balance? Not sure how to measure it. 30" or 31"

3rd photo is a roller on a pot metal arm with a screw in it. Placement is on bottom left of lower window.

This is a spiral balance. We can help replace it, but we need to know the exact diameter and length of that outer tube. The component it attaches to is called a pivot shoe. Yours looks pretty damaged, but if you can pull one out of another window in the house (preferably identical) and tell us the width and thickness of the shoe, we should be able to replace it as well.

Hi Bob ~ Thank you for your response. I will be placing an order soon. Do you recognize this aluminum window lock? Is there a different lock available to take it's place?

Unfortunately I don't think we have a replacement for this sliding window lock. We don't have anything that matches its end profile, which leads me to believe it may be a type that is no longer made. You can view our selection here. A local hardware store may be your bet. Apologies that we cannot be of more help on this one.

Hello again. This looks like an older version of the 15-015 to me. This shoe is 17/32" thick and 1-1/4" wide. Let me know if your shoe's dimensions are the same, or if they differ in any way.

Thank you for your response.
The only difference I see is that there are two (2) angled off centered slots on the 15-015 and a single centered slot on the one I have. Just guessing, could it be 15-118 shoe? Does the centered slot make a difference over the off-centered slots? Please advise. Thank you.

Personally I've never found the angle of the slot to be an issue when it comes to installing a spiral balance with this shoe. Not to mention, the 15-015 was meant to replace your very same older Acorn pivot shoe. That said, the 15-118 does have the same dimensions and does have the center slot; but it is a different enough style that I'm not sure if it would fit your window track.
