Replacement Window Sash Balance

Question

I need to replace Window Sash Balances for 16 windows. Size and weight of windows:

1 is 48" high X 36" wide / Each window (top & bottom panes) weigh 45 pounds.

others are 36" X 36" / others are 48" X 34"and weigh less than 45 pounds.

These are wood frame window, double pane windows with 5/8" laminated & tempered glass outside panel with 1/8" inner panels.

Do you sell Window Sash Balances for these sizes and weights windows?

Photos of the Window Sash Balances we need to replace for the 48" X 36" (45 pound) windows are attached.

The windows were manufactured in 2003 by TM. Cobb company.

Thanks! Carl

Hey, Carl. It's hard to make out your balances from your picture. Your stamps are also a little weird. Start by looking at our Series 751 and tell me if this is similar to what you have. The defining detail of this balance is the bottom shoe at the end of the cord.
