Thanks for posting, Ian. It looks like you have a Chamberlain window that was made in the late 1980's. You are right in observing that the sashes aren't made to come out. It's frustrating, but that's just how these windows are made. We have a way around that, but let's talk about the balances first.
I see you bought our S500-23 spiral balances. Did this match your old balances? If so, you will need to reuse the old sash clips attached to your window. I actually see them still installed in the sash. You might need a pair of needle nose pliers to straighten out the fork that catches on the balance bow tie. As for balance installation, you will need a friend. With someone helping you, you will need to drop the new balance in from the top of the sash, screw it in at the top, then let the spiral drop down. You will then raise the sash and, while someone holds the sash in the open position, spin the spiral up to the bottom of the sash. Finally, with our 75-004 tool, give the balance about three turns to charge it and lock it to the end into the sash clip. Let me know if you have any more questions. |

Great! Let me know how it works out. Hopefully it goes smoothly. I know it can be a pain, based on the very design of this kind of window, but with a little patience and elbow grease it should work out. Feel free to contact me if you need any assistance.

That's awesome news, Ian. I'm glad the hardware matches. As for the friction, use a silicone spray or wax and see if that helps. If not, it's possible you need some sort of face guide like our 67-002. These install on the edge of the sash so that it rubs against the master window frame.
