Black tube spiral balance

Question

I have 4 spiral balances that are 30 inches in length and 3/8" in diameter. They are for tilting windows that have a sash weight of about 30 lbs. . When I removed the balance the spiral fell out. There is nothing broken on the spiral and there is nothing inside the spring to hold it in. The balance has a white tip and the windows are about 3 years old. Any information you can give me will be greatly appreciated.
Thank You

Thanks for posting! Just to confirm, the diameter you're measuring is the outer plastic tube, correct? That's the one you want to measure. If so, then you're looking at a Series 900 spiral balance. However, we don't have a standard tip color for a 30" Series 900 that can support a 30 pound sash.

I recommend going with our Yellow Tip. Two balances with a Yellow Tip can carry a window sash weight range of 24 through 34 pounds. If you want to go that way, it'd have to be a custom order. If that sounds good to you, let me know and I can get the ball rolling on this.
