How to use

Measure and confirm the door backset is 30 or 40 mm and verify compatibility with the existing mortise lock body. Remove the existing handle set following standard door hardware removal procedures. Position the Zabi WK30/40 H handle set so that the symmetric rose or escutcheon aligns with the spindle and screw holes, then secure with the supplied fixings or appropriate screws. Check spindle engagement and handle operation; adjust mounting screws if necessary to ensure smooth rotation and correct latch operation.

Usage recommendations

For best results, clean the finish with a soft, damp cloth and mild detergent if needed; avoid abrasive cleaners or solvents. When replacing handles, ensure the mortise lock latch and strike plate are aligned to prevent binding. For high-traffic commercial applications, verify the handle set meets local durability expectations and consider periodic tightening of mounting screws.
