SWISCO - The Replacement Hardware Authority

spiral balances from a retrofitted wood window sash

A contractor from Columbus, OH - New Orleans, LA says:
I'm working on a window restoration project in New Orleans and many of the historic wood sash have been retrofitted with spiral tube balances which I need to replace.
Most are 5/8" and bettween 2' and 3' long; however, (4) are 7/8" dia???
The attachment device (angle/clip???)at the lower end is a bit awkward.
I've included photos.
Do you have products that might match?

Kurt, take a look at our Series 500 Spiral Balance. The bracket would be the Swisco 17-007 Bracket X54.

Also, when picking out the size of your balance, be sure to measure the length of the spiral portion of the balance only:
