Master Lock 3-Pack Keyed Alike Trailer Coupler Locks

This 3-pack of Keyed Alike trailer coupler/tongue locks is the ideal solution when in need of multiple locks that utilize a single key. The same key can open all three locks, and each lock comes with two keys, resulting in a total of six keys with the purchase of this set. Additionally, the locks are backed by a Limited Lifetime warranty.

ATTENTION: It's important to note that if you order two 3-packs, they may not necessarily be keyed the same. To ensure that the two 3-packs are keyed alike, you must order the 6-pack instead.

These locks are designed to protect unattended trailers and guard against tow-away theft. The universal trailer coupler lock fits a range of common couplers, including 1-7/8in (48mm), 2in (51mm), and most 2-5/16in (59mm) couplers from manufacturers such as Reese, Fulton, Valley, Atwood, Shelby, Putnam, Hammerblow, Dutton, Lainson, and UFP.

The simple yet effective design of these locks makes them difficult to defeat. When locked on the trailer, the lock rests on top of the coupler, thwarting blunt force attacks from downward hammer strikes. Furthermore, the lock's ability to rotate (less rigidity) makes it harder to break with sledgehammer force.

Featuring a rekeyable cylinder for keyed-alike convenience, these locks also boast an advanced locking mechanism that resists picking and prying. Each lock weighs 2.4 lbs. and is easy to install and remove.

Crafted with Reinforced Zinc Die-Cast, these locks are resistant to rust and corrosion. Zinc alloys are known for their exceptional strength and toughness, offering higher impact resistance compared to cast aluminum alloys, plastics, and grey cast iron. With tensile strengths up to 60,000 psi and superior elongation, zinc alloys provide the necessary strength and formability for strong designs, as well as versatility in bending, crimping, and riveting operations.

In summary, this 3-pack of Keyed Alike trailer coupler/tongue locks provides a convenient and secure solution for protecting your trailer from theft. The universal fit, robust construction, and advanced locking mechanism make these locks a reliable choice for safeguarding your valuable assets.
