Old window locks, unidentifiable

These windows are impossible to identify, but I have replaced the "dead" spiral balances with your products (thanks!) so I hope you can help me with this, also. One of the locks has a broken lever so I need at least one.

This is definitely an old style lock. We may be able to track something down, though. Before I recommend anything, can you confirm the distance between the two installation holes, center-to-center? That would be for both the lock and keeper.

If it's 2-1/4", then you could possibly use our 90-005 lock and 90-109 keeper. These mismatch a little but they are compatible. You could also paint the keeper, if necessary.

Let me know what you think, or if you have any concerns.

It's actually 2-3/4" between screws, on both lock and keeper. It's a 5/8" distance from keeper screw to lock screw when both on the window. Both units are about a half inch tall. Other ideas?

Thanks for confirming that measurement. I'm afraid we don't have anything with a hole spacing that large. Every sweep lock we carry has a hole spacing under 2-1/2", and most vary between 2-1/16" to 2-1/4".

Is redrilling your installation holes possible? I know that's not ideal, but we just don't have anything closer to the size you need. I apologize for the inconvenience.
