Spiral Balance Assistance

A quick learner from San Diego, CA says:
I need some assistance identifying the parts I need to replace my spiral balances. This is for a non-tilting window.

Spiral Balance: 3/8" x 29"
Shoe: I think it is your part 15-142.

I am unsure of the color code, but it is a dual pane window measuring 27" x 30".

Thank you for your assistance.

We should be able to custom make this balance for you. I would be using our S900-29 spiral balance with a 15-142 shoe. Let me know if this hardware matches. If so, I would like you to confirm two things:

-The weight of your sash
-How many balances you need

Once I have this information I will send you a custom order form and price quote.

My sash weighs about 18lbs.
I need just two balances as I would like to see if I am successful before tackling my other windows.
