This lock is missing The lever. The exterior piece and lock handle are plastic. The overall measurement of the exterior piece is 3- 1/4"..the screw to screw measurement is. 2 -1/2". The mechanism part that moves the vertical lock up and down is 5/8" Wide, I can't tell how long it is without taking piece out. If you need more information let me know, thanks.

Hello!
This resembles our 38-090 SilverLine casement locking handle but we recommend you compare our dimensions to your part to confirm everything aligns for what you need.
