Printing on handle is Cmech and is in a EMCO Store In Door Crossbuck Door. Serial number is 0007475366. The part # is the set up guide is 608413 but I cannot find it anywhere. The pin is 5/16 and there is 1" gap between the latch and the door(noted in picture). If you can help with this it is appreciated.

We don't carry this exact handle, but check out our 40-150 and see if you could adapt this to work in your door.
