770 series with T-Lock Balance Shoe

Question

I have what appears to be a Series 770 29" balance stamped 29C BSI KH where the BSI is vertically imprinted between the C and the letters KH. My channel depth is ~1/2" and width seems to be ~1.25" wide.

I need 2 new bottom shoes. I did use screwdriver and turned black circular piece in Picture 1 counterclockwise to release shoe, and then was able to slide old shoe up in the channel. Looks like my old shoe could be your 1-1/4" T-Lock Balance Shoe, Product Code: 15-195.

Picture 1 is from the broken bottom shoe. Picture 2 is same broken shoe with me holding piece I think came from shoe. I wasn't sure.

Picture 3 is from intact portion of top of bottom shoe from existing working window. It doesn't seem to be precisely same as your product code 15-195.

Questions:
1) I can't get broken bottom shoe out and I'm not sure your spreaders will work as frame seems pretty rigid and there is no slot in frame to slide out the shoe. Any other ideas I might try? If I do want to try spreaders, maybe Swisco could do free loaners on spreaders with deposit and refund deposit when spreaders are returned? Kind of like a core charge on car batteries.

2) What is steel piece I'm holding in picture 2 go to?

3) Do you think your part 15-195 will work for me?

Thanks for posting. Yes, I believe that our Series 770 appears to be the right match. You cannot use our 15-195 shoe with that, however. The 15-195 is meant to physically attach to a very particular channel balance. It does not work like other pivot lock shoes.

I think your shoe is something closer to our 15-121. Take a look and let me know what you think. That metal piece is a part of the shoe that has broken off. You can see that very same piece on many of our pivot lock shoes, including the 15-121 for example.
