Could a Master Lock 1-7/8" and 2" Trailer Coupler Lock # 377DAT Be Ground Off by a Grinder


I own a small travel trailer and I also own a 28 volt battery powered grinder. I also have a diamond wheel for my grinder. Is this lock resistant to a battery powered tool?


Helpful Expert Reply:

The Master Lock 1-7/8" and 2" Trailer Coupler Lock # 377DAT that you referenced is constructed of steel, which will make it harder to cut off then an aluminum coupler lock. But if a prepared thief had a battery powered grinder like you with a diamond cutting wheel it would only be a matter of time before he could grind the lock off.

You have to consider that the odds of a thief having a grinder like this are pretty slim. Plus the fact that the amount of noise created by grinding on this lock would deter all but the incredibly bold (or drunk) as thieves generally don't like drawing attention to themselves.
