Left or right hand 38-065 cam handle lock

The opposite side of the 38-065 is the 38-064. "Left" and "Right" handed locks like this are actually defined differently from manufacturer to manufacturer. Some companies define it by what side the lock sits on, while others may define it by the direction in which the window opens. There really is no industry standard.

The best way for you to determine what lock goes on which side is to compare your hardware to the pictures we have on our site.
