Window too heavy and cannot be reinserted into feet of balance.

A home owner from san francisco says:
The upper window on the right in pic 2818 will not stay up and is completely disconnected from the balances on both sides. the lower window it is extremely difficult to insert the feet into spiral balance even using your instructions of pulling the window part way up. By myself I cannot do it. These windows were installed in the 1980s I believe. If I buy new balances and feet, will it be easier to insert the feet into the balances? Also would all the balances be exactly the same in similar height windows? The measurement of the balance is 28.75" not 29" or 28" (not including the plastic part at the bottom). I assume I should order 29" spiral balances, not 28".

Thanks for posting. I'm not sure I understand the issue you're running into. When you say feet, are you referring to the rectangular pivot shoe that connects the sash to the balance spiral? If so, could that be all that's broken, or are you confident that the balance is the problem?

Since you have a tilt window, you can use either our S600-29 or S900-29, depending on the diameter of the spring. I don't know any company who made a 28-3/4" long tube but you should be fine rounding up.

You should measure the metal channel for each balance that needs to be replaced, just to be 100% sure.
