Tube balances

Question

To whom it may concern;

I am trying to determine the correct color tips for Tube Balances. All my windows have he same color tip. Window are metal with 2 glazing inserts, sizes range from 14" x 23" to 36" x 30". I am afraid to remove the units and weigh them due to the fact that if the Balance Pivots break, I will be unable to get the window back in the sash. The windows are in an apartment building so I guess they are commercial grade.

Perhaps I need not worry, I do not fully understand the design criteria for choosing the correct resistance based on the unit weight, but do you have any guide lines I can use to possibly or only several Tube Balances.

In one upper window both Tube Balance have failed and the window can't open without dropping to the windowsill, this window is 30" x 33".

Thank you in advance for any assistance you may be able to provide during these hard times.

Hello,

The tip color indicated the tension the spring requires to keep your window up based on the weight of your sash. You can either choose the same tip color as your previous balances or you will need to weigh the window sash and follow the chart under the product description for the balances you plan on ordering to choose the correct tip color. Also, keep in mind that spiral balances do not come charged, so you'll need to order a charging tool for them as well. We will also relate some videos and information that you may find helpful during the replacement process. Thank you!
