High quality, great price, fits variety of trailer ball szes
Master brand is known for high quality, which usually comes with higher price than competitors. Lots of research done to find a very solid lock for new camper trailer. This lock was reasonably priced, in line with other 'foreign'-named options. Lock arrived quickly AND much better theft protection than a lock through the trailer latching mechanism.
