The G-U 20mm faceplate for Superior Doors has been discontinued. 
Replace with 499060019 

Ferco G-U made some custom 3-point Shootbolt version locks with a wide 20mm faceplate for Superior Door and possibly few other manufactures. 
This 20mm faceplate width is no longer offered by Ferco G-U. 
The gear box on the old style and new style are NOT interchangeable with new style locks. 
The most common use of this Multipoint lock was on Superior's Vinyl Patio Door. 
The old style locks have a 2 inch (50mm) backset with a 25/32" (20mm) gold colored faceplate.
