Thanks for posting, Pete! These balances appear to be similar to our tilt-window Series 600 spiral balances, whose diameter measures 5/8". Does that look about right?
Now, as you can see, the length of our balances are determined by the balance tube only. The spiral protrusion is not counted in this measurement. Could you double check your length based on this information and let me know what you come up with? Could you also tell me the weight of each sash that these balances support? That will help us determine their tip color, which will in turn determine their strength. You may also want to look at our 26-200 Balance Screw Plug. Does that look like it could be useful? |
