A rep who now are the contact for our Simonton Luminess 400 series windows provided the following. Our current local window contractor/company stated we needed a new "balance shoe" for a double-hung window.
'The part number or balance sizes you need are 3.5 Omega and 5.5 Omega balances. They are for a Luminess 400 series window and the date manufactured is 6/2002.'
I can be reached at day or evening. I hope to discuss & verify what's needed as well as the cost.
Thank you for your help.
