First, wondering if you sell the window stops, as pictured in the attached.
Second, despite cleaning. lubricating and many attempts to adjust the spiral balance on our windows, most are still difficult to move, and removing is just as problematic. While I can eventually brute one side of the window up and angle the widow out, returning it is even more difficult.
When I remove the windows from the spiral balance and move the balance shoe manually, but twisting the notch, it moves quite freely. So, it doesn't appear to be an shoe issue...or does it?
One of the windows had broken stops, so the upper sash went beyond it's length, and pulled out of the balances. So, I've ordered replacements that should arrive in a week or so. Sorry, it was from Home Depot, before I discovered your amazing website.
So, we'll be replacing the both balances in that one window, which may lead us to a solution to the rest. However, it seems unlikely that nearly every window could have bad balances, leading to this epidemic.
Can you advise on some steps to take, to eliminate culprits?
I've attached the installed and removed stop, as well as the only identifying tags on the windows (inspection and specs)
Thanks,
D. Foster
