1-1/4" T-LOCK BALANCE SHOE, OPEN CAM

I bought some of your 1-1/4" T-LOCK BALANCE SHOE, OPEN CAM to replace them in my windows. As it turns out, while the parts are generally the same, the new part is deeper at the top, where it fits into the spring balance. As such, I can't get the hooked part around the wire to secure the shoe, and the shoe itself is too deep to fit into the balance. Is there another shoe that is substantially similar, but a little less deep?

Paul,

Thank you so much for directing me to the 15-236 T-Lock Shoe. I bought a few and they worked perfectly. I then ordered 40 more and replaced them in every window of the house. I had two window companies give me quotes to repair the windows, one quote was $2,100 and the other $2,500. The parts cost me $80 thru Swisco and my wife and I replaced the shoes in all of the windows in one Saturday. Again, I cannot thank you enough for your help. I will recommend Swico to all of my friends.
