Window Balance Part Identifying

A handy person from Jacksonville, Florida says:
I am in the need to replace a few window balances and top sash guides but don't know what to order. I don't know the brand of windows.
The balance is 1/2 X 25.
It has the following stamped on it 24 9 GX CMC 7
I also have attached several photos
Thanks

Thanks for posting! Before I can offer an applicable replacement for this channel balance, I just need to know a bit more information about the bottom attachment. Please take a look at our 15-004 and 15-005 channel balance shoes, and note their depths. As you can see, they are 1-3/32" deep and 1" deep, respectively. Which one more closely matches your own bottom attachment?

Can you also weigh your window sash and let me know what you come up with? Unfortunately, your stamp of 24 9 does not match any of our available options, and so we will need to know your sash weight in order to determine what you need.
A quick learner from Jacksonville, Florida says:
The depth of the shoe is 1". The weight of the window sash is 29 lbs.

Thanks

Thank you. For a sash of that weight, you will need to choose the 2460 option, which can support a window sash weight of 27 through 30 pounds.

Finally, in regards to your top sash guide, take a look at our 18-166. I can't know for sure if this will replace yours without knowing your exact dimensions, but compare it to the 18-166 and see if they match up.

Thank you your help. I looked up the top sash guide 18-166 and the dimensions appear to match the one I have.
Again thanks
