These instructions will assist you in reversing a Cosmas Entry Door Lever, including the Cosmas 50 Series and Cosmas 80 Series. Other Cosmas Entry Door Levers are symmetrical in design, and would not need to be reversed.
Unpack Cosmas door lever from box
If necessary, remove old door hardware from door.
Insert and install latch.
Insert lever with spindle into latch, making certain that stems are positioned correctly through latch holes. Push flush against door. Insert screws and tighten until lock-set is firm.
For keyed entry levers, make sure that key cylinder is on the correct side of the door, even if the lever is temporarily upside down.
To reverse the door levers, set the lock button at 45-degrees between “lock” position and “unlock” position. NOTE: It is important that the lock be in this position in order to remove and reverse the levers.
Use a flat-head screwdriver, or included tool, to depress the tab on the exterior trim. This will release a catch and allow you to remove the exterior lever by pulling away from the door. Repeat the procedure to remove the interior lever, making sure the lock is still in the correct position.
Exchange the interior and exterior levers, placing the interior lever on the outside and the exterior lever on the inside.
Depress metal tab, and secure the levers until they “snap” into place over the tab.
Install strike plate.
