Alumax Replacement Parts

A home owner from Valley Village, CA says:

I am looking for two of each of these parts. One is shorter than the other. The windows are Alumax and I believe they are used to open and close them.

Thank you.

Hello! For the spiral balances, can you check the diameter of the outer white tube? If it's 3/8", I recommend our Series 900 balance. If it's 5/8" or 9/16", see our Series 600 instead.
