2) Ft. Knox Locks Gooseneck Lock - Best for security

Boltcutter-proof yellow gooseneck trailer lock from Ft. Knox Locks


This high-security gooseneck trailer lock from Ft. Knox Locks puts its boltcutter-proof qualification at the forefront of its specs. Also, it fits most gooseneck couplers, including the new low profile Bulldog BX1 round drop tube (but not the square BX1 version), and both round and square drop tube style couplers. It is constructed using welded steel. Lastly, with a bright yellow powder coat finish, this lock is definitely hard to miss.

The square opening on this gooseneck lock measures 4-3/4" on each side. Moreover, it works well with most puck-style locks.

According to the manufacturer, only high power tools and a cutting torch can possibly stand a chance against this particular model. To add, it also comes with a limited lifetime warranty for all manufacturing defects, which is reassuring given the price tag that it comes with.

What Buyers Like

The construction of this product is certainly heavy, and for some users the bright yellow aesthetic screams "highly-secure" and "impossible to steal" -- something that really helps ward off thieves. Although its heavy body makes it challenging to hold, it's not too hard to use it in general as far as locking and unlocking is concerned.

Final Verdict

The price tag on this lock can understandably discourage frugal shoppers. However, if you're on the market for the most secure gooseneck trailer lock and you don't mind paying extra bucks for more peace of mind, then this Ft. Knox Locks product is the one for you.

Furthermore, its solid stainless steel design looks sophisticated enough to ward off thieves. It's also pretty easy to handle and install because the lock itself is quite small. Finally, the fact that it costs only a few dollars above twenty bucks is a massive plus, as well.
