What we have done here is to take the heavy duty Maser 6230 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 6230 lock is almost identical to the famous American A700 padlock, and since Master Lock owns American Lock, it isn't surprising. The only real differences are that this heavy duty lock has a Master Lock cylinder and the cost.

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".


Available in Keyed-Alike sets (specify below).

NOW AVAILABLE - This lock comes standard in non-key retaining format. We now offer key retention as an option. If you select key retaining (below), we will reconfigure the lock so that the key cannot be removed unless the padlock is locked, thus helping to prevent the lock from being left unlocked.
