Ulltimate challenge 6 pin euro practice lock
is a brand new, solid brass, anti drill, 6 pin Euro cylinder cutaway practice lock, fitted with 6 security pins.
This is the Ultimate challenge lock, fitted with 4 different types of security pins, including one serrated pin. (6 Pins in total)
This solid brass lock has been cut and machined to a very high standard to expose the inner workings of the lock, enabling you to see both sets of pins, the springs and the shear line.
The shear line is where the two sets of pins line up to allow the lock to open. Being able to view this is very important when learning how to manipulate a lock!
These locks are precision engineered to ensure that the springs and pins cannot fall out of the lock with normal handling.
