Medeco Protector series 50
The design and materials used on this lock are top notch except for the relatively thin and weak 11mm stainless shackle which disqualifies it for my intended use. I was led to believe it had a 13mm hardened shackle, again, should have done more thorough research before making the buy. I cannot work out why in the world they would make amassive lock full of hardened rods with a top loading six pin Medeco cylinder then use an 11mm stainless shackle that can be very easily cut. I suppose it was meant to be used with a protective hasp in an outdoor environment perhaps? That's the only possible explanation I an come up with.

The core
I did not realize that the original Medeco key pins have milled gates and not the broached gates that have been exploited in the newer cylinders.
