Thanks for writing in. The first thing to check with these tilt window spiral balances is to see if 'charging' them will fix the issue. If you need a charging tool, see our 75-006. Remove the sash from the window, then give the spiral balances 3 or 4 rotations to charge. Put the sash back in. If it still fails to stay open, try charging the balances 2 or 3 times more, but no further. If they still won't stay charged, that's how you know you might need new balances or new shoes. If the old shoes are broken, we'll need to see one out of the window, and we'll need the width and thickness. For the spiral balances, will need either our Series 600 or Series 900. Let us know if you have any questions. |
