S500-30 spiral balance

A home owner from jersey city,nj says:
1. For a window with a lower sash of 34" wide x 34" tall and a top sash of 34" wide x 33 " high, what would be the correct size for spiral balances? 2. I would like to order S500-30 spiral balance but the spiral balance I am replacing has a black tip. I don't see a black tip in your catalog.
Thanks,
Ira

If you originally had black tip 30" Series 500 balances you should replace to just that; I have added the Black Tip option for you, here is a product code link to get you started: S500-30

The 30" Series 500 Balance with Black Tip option will carry a window sash weight range of 31 through 40 pounds.

This information is based on 2 balances per sash. Balances are designed assuming friction in the jamb weather-strip will carry a portion of the sash weight. Suggested sash weights are approximate.

Hi,

We have tilt-in aluminum windows that have sash that are approximately 45"w x 39"h and weigh 44lbs. The old cord balances are about 38" long.
Can new 38" black tip balances support that weight?

Can you give us the length of the spiral portion of the tube only?
