replacement parts.

A quick learner from Portersville PA says:
Hello.
so happy I found this site.
I am trying to repair two Trayco windows from the early 90's.
smaller window, 31x20, has one "mouse" with a spring labeled "7"
I think I got that 15-087.

The larger window has one Mouse, and two extra cartridges all with springs labeled "5".
My question is how do I connect the extra spring cartridges'?

Hello!

It sounds like you may be referring to the 15-086 tandem coil housing which simply connects to the 15-087. Let me know if this helps!
