What is the difference between a Grade 2 and Grade 3 Lock?
The grade three has to go through a two hundred thousand cycle test, that doesn’t mean that the lock could go to five hundred thousand, but it had to pass the two hundred thousand cycle test to be approved to be a grade three. Grade two has to go through a four hundred thousand cycle test, which is double over grade three.
