Changes and additions
Additions
Lock function Additional available feature Notes
All functions Hassle free inside anti-rotation plate
installation
Improved door thickness adjustment
Lever catch wear remedy
Installation of the inside anti-rotation plate is aided by an insert on the inside
hub allowing for hands-free installation.
Door thickness adjustment is more straightforward with the redesign of the
outside housing and the addition of a gauge insert.
A spacer is added on inside and outside spring cage assemblies to provide a
more firm lever fit, thereby reducing wear on the lever catch.
