This stylish patio door handle set comes with 10 inch matching inside and outside white handles with an offset thumbturn/lever. It can be used on either right or left-handed doors. It is used by many patio door manufacturers. The white diecast lever operates most mortise latches installed in the door (see Prime-Line parts E 2008, E 2009, E 2014 or E 2111). This is non-keyed but can be keyed by installing the Prime-Line part E 2195 cylinder housing onto the outside handle or replace the outside with the Prime-Line part C 1120 keyed outside handle. Minimum door width of 1-3/4 inch and maximum of 2-1/4 inch (mortise lock is sold separately).
