Spiral Balance Color Help

These white colored tips on spiral balances are from older ratings systems, and they're generally not reliable to go by. What I recommend you do is that you obtain the exact weight of your window sash. You can then match that weight with one of the weight ranges listed alongside each color tip option on the spiral balance shop page. 

Sorry to hear the Series 900 did not work out for you. You may view our Return Policy here. Before you order another balance, can you give us the diameter of the plastic tube that surrounds the coil spring you are showing in the photos? That way we can confirm if you indeed need the S600-29. You will need to obtain the exact weight of the window sash to determine the color tip option you need. In regards to the separation between the rivets, may we see the pivot shoe your window is using? That will help us determine the best course of action. Many thanks. 

Hey Robert. Your caliper reading is still a bit unusual to me, because it's roughly close to 7/16", which would be closer to the diameter of the Series 900. That said, in your photos the older balance does appear thicker to me. The diameter of the Series 600 is 5/8". The issue is with these older spiral balances with white plastic tubes is that the tubes tend to warp and break over time, so getting an accurate diameter reading often is difficult. Do your best, even with measuring tape, to try and see if 5/8" is closer to what you have.

If so, then you'd need an S600-29 with a Red Color Tip option, which is for a window sash in the weight range of 7 through 29 lbs. Let me know what you think.

Hi Robert. I understand the difficulty here; with these older spiral balances, getting the diameter of those white tubes can be really tricky, especially when they've deteriorated. Let me know how you make out, and if either of these choices still aren't right, we'll keep working with you to find another solution. Thanks again for reaching out.
