Very heavy and nice quality door lever. I updated my old round knobs, replaced by myself with the help of a screwdriver . Door lever is reversible so you can put it to the right or left . Comes with all the pieces you need , even comes with 2 strike plate options , one is rounded and the other one square. I had some of my doors needed rounded and some square so that was really nice to have. My only issue was some of my doors didnt have enough depth for strike plate and some needed adjustments. After placing the strike plate into correct position door locked and worked very well. Happy with my purchase
