Thanks for posting! Before I can recommend an appropriate replacement for your Spiral Balance, I just need to know a bit more information. First, what is the length and diameter of the tube for your spiral balance? Then I will need to know the weight of your window sash. Let me know!
You may find this tutorial video on how to replace a tilt window spiral balance somewhat helpful. |

Thanks for getting back to us with the details! It sounds like you might have one of our Series 600 spiral balances. However, our balance lengths usually end on the inch, not on a fraction. Could you confirm the length of your tube? Make sure not to include the plastic tip or the spiral protrusion in your measurements!

Awesome! That will make things a lot easier. I appreciate you double checking for me. Now, as I said before, it sounds like you have our Series 600 spiral balance; please look at our S600-13. For a window sash that weighs 13.5 pounds, I recommend our red color tip option. This tip will carry a window sash weight range of 6 through, and including, 18 pounds.
Please keep in mind that the weight range 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. |

The charging tool you would want is our 75-006, for tilt-windows. It is probably wise to just try charging the balances you have now first. In many cases, that is all the service that is required. However, if while charging you don't feel any tension, or if the windows still droop, the balances will likely need to be replaced.
The plastic part you are referring to is known as a Pivot Lock Shoe. It is not necessary to replace them when you replace your balances, but if they look worn out or damaged it wouldn't be a bad idea. |
