What we have done here is to take the heavy duty Maser 6321 padlock and replace the standard 5-pin cylinder with a 4-pin W1 cylinder that we can key alike to match many other Master Lock K1 keyed products such as receiver locks, trailer coupler locks, etc.
Granted, you lose a little security going from 5 to 4 pins in the cylinder, but thieves rarely attack the cylinder anyway and anyone trying to pick it is going to get really confused since they will be expecting a 5-pin lock. What you gain is a much heavier body and shackle than is otherwise available in a 4-pin padlock and it is the shackle that thieves most commonly attack.
The Master Lock 6321, 6325 and 6327 are some really touch locks. Inside, there is the proven reliability of a Master steel laminated lock with a boron shackle. Outside, a weather resistant case and iron shackle shroud. Wow, this is a hoss of a lock!
Uses a Master K1 Key and can be matched to many other Master Lock products in our inventory: see our section on "Keyed-Alike Locks".
