The NL redundant locks - first peek
I bought some NL redundant locks ( I believe they are marketed in the US as LP locks, Loss Prevention), and to my understanding the man behind the NL locks of the Netherlands (Nick Gartner) was the prior owner of La Gard.
One of the LG's is a swingbolt, the other a deadbolt. The deadbolt version is much thicker than standard, and will have installation issues in some containers.
Anyway, these locks was not purchased to manipulate, but to replace the locks on my gun safes. My country requires gun safes that are more like the US TL-15 ratings, and the locks also have to be certified. Thus the Securam Xtreme that I also bought, could not be used as it had slipped my attention that the mechanical side of this redundant lock is not certified at all. The certification they boost are only relevant for the electronic side of the lock. Questionable marketing in my opinion. No dual lock is more safe than that of the weakest lock provided.
The NL's:
I'm not an expert so take my comments as my newbee understanding of how this works.
I think the pivot locker will get into play when excessive pressure is applied to the boltwork, like smashing the opening handle. The swingbolt will then pivot and lock into the "gears" machined to the case and the swingbolt. That would be a safeguard to safes with inferior boltwork that does not provide a break pin or clutch drive if subjected to brute force.
I find it strange that this is a 2M rated lock. Most 2M locks will have an extra arm inside that lifts the nose away from the cam until it is over the drop-in point, keeping it from being able to touch the contact points and disallowing measurements like you'd get on a Group 2. This lock has no such contraption. Never the less, I tried measuring change in contact points while gate was over a combination dial, but could not read any differences. I don't know how this is done, as it seems the fence is riding the wheels. Close manufacturing tolerances? Or is it enough to be rated 2M to have 4 wheels vs 3? Someone with more experience, please chime in.
