Spiral Balance Help
Hello,
Unforutnately, the company that made your balance system is no longer in business, but we can still help. You'll need to use the Series 500 non-tilt balances to replace the originals. To get started, you will need to measure the tube length of the original balances. The bottom bracket with the nylon guide is also not available, so you will need to use the 17-012 with the S500 balances. As for the nylon guide used to keep the sash square to the window, see the 67-002 face guide. The window will use two for each side of the sash. Thanks for posting.
Sure, you can use the Series 600 balance and the 62-001 rivet. You'll need to knock out the two pins in the spiral balance end in order to attach your original bracket.
