Lock ID Help Needed - Pin-in-Pin Tubular
At first blush, it looks like a 7 pin tubular; however, upon closer inspection one can see that 4 of the 7 pins are pin in pin, much like a Mul-T-Lock. Close inspection of the key reveals that there are different cuts for the inner and out pins. Very cool! In addition, it appears to be UL rated (presumably, UL437?). As far as picking goes, it is certainly harder than a normal tubular lock, but not by that much. My google-fu revealed that HPC used to make a tool for opening this lock. The marketing materials I found from HPC says that it’s supposed to be “unpickable,” but the maker is not named, nor could my best efforts find it. Any help would be appreciated.
