ABSTRACT:
In a ladder leveler of the type manually actuated through a clutch plate to free a leg extension for adjustibility purposes, a protective guard is applied to the clutch plate in a manner to preclude forces being accidently applied to the clutch plate when the leveler is in use to thereby avoid possibility of tragic accidents.
