Installation Info
DOOR & FRAME PREPARATION:
 
  Note: To assure lift-off capability, 
  the lower knuckles must be installed on frame, upper knuckles on the door.
  
  
Note: For non-lift-off mounting, one upper knuckle 
  and one lower knuckle must be mounted to frame. One knuckle must be installed 
  AFTER door is hung. For non lift-off offset hinges only: Use one type “A” and 
  one type “B” hinge per door.
