Thank you for posting! I'll answer your questions one at a time.
1) The pulley wheels on our balances are plastic. They are not able to be replaced or fixed; if they are broken, the whole balance has to be replaced. 2) No, it is highly recommended that you only get the balance option that supports that window sash weight precisely. If you go any lighter or heavier, then it will not function properly and will likely become damaged. 3) I'm not sure what Series you have, so I can't speak for the availability. But you're right, if some balances are starting to break then it may not be a bad idea to prepare for future repairs. |

Mike,
Please note, the Series 795 Channel Balance comes with the 15-195 balance shoe (1-1/4") wide for replacement windows, but you can order this with the 15-194 balance shoe for prime windows. At this time, the balance is still popular with window manufacturers, so I would say at least another five years. As for the mesh, there is no aluminum screen that has a tight enough mesh to keep out tiny insects like gnats. Even if you can find something small enough to prevent tiny insects from entering through your screen we always recommend keeping your lights low to prevent any attraction. |
