Will 38-139 replace my casement lock

A quick learner says:
I think your part 38-139 is the closest replacement. The little arm that moves up and down is a little different shape, but i am thinking i cant get an exact match because the part is so old? I wanted an exact match because the lock right next to the broken one is fine, so it will look a little weird that they dont match exactly.

The 38-139 certainly looks like a good match, though you would need to confirm that the dimensions we show are the same as yours. As for an exact match, I'm not sure if that would be possible, especially if yours is an older model. Many manufacturers completely discontinue their older lines for newer models.

I just realized that because the handle on the lock is broken, I cannot open the window in order to unscrew the broken lock and replace it. Any ideas on how I could do that? The handle just pulls off. When I put it in and turn it, niothing happens.

That is a tricky problem. Try to see if you can throw the lock with a screwdriver. If you are unable to do so, you will need some way to cut the old lock off. In that instance I would highly recommend contacting a local handy person for assistance, as it is no easy task.

I just got the part and it fits but the old screws are too thick. And the old paet had threads for a screw to go in, and the new part does not. How do I attach it?

Sorry to hear you're having trouble. See our 33-096 self tapping screw, I think this should work.
