72/40
I learned this evening that the 72/40s with this keyway are significantly easier than the other ones. I’ve had one of the other ones for a few weeks and I keep coming back to it in and among others, but haven’t managed to get an open yet. I recently got six of these, keyed differently, and popped all six this evening without breaking a sweat!
I also learned that they, like the 1100, don’t turn once you’ve unlocked them until you up the tension considerably! I unlocked two of them without realizing it at first.
