Why Consider A Custom-Fit Lock?
Custom-fit trailer hitch locks provide a superior level of security and peace of mind compared to generic locks, making them a worthwile investment for anyone who wants to
strongly protect their trailer from theft or tampering.
strongly protect their trailer from theft or tampering.
Custom-Fit Locks Benefits
RESISTANCE-DRIVEN DESIGN
While conventional trailer locks can be easily broken in seconds because of their u-shape and poor resistance materials, AMPLocks take accurately the shape of your
ball coupler to form a massive and custom-fit shield, made of high-grade North American materials.
Boasting superior mechanical properties, materials used by AMPLock offer remarkable capacities such as extreme resilience and huge resistance against any kind of attacks, from brute force to cutting with portable power tools.
Reduced Risk of Damage:
Generic can potentially cause damage to the trailer's hitch or locking mechanism if they don't fit properly. Custom-fit locks eliminate this risk by ensuring a precise fit, minimizing the chance of damage during installation or removal.

DETERRENCE SUPERPOWER
Long Range Security:
The presence of a custom-fit lock acts as a visual deterrent to thieves, as it implies higher difficulty and risk. we bring it to a whole new level with our patented designs, turning any attempts of stealing into a long and painful efforts.
What If They Try Anyway? Wish Them A Good Luck!
Open the lock without the key would require very
specific tools and skills:
Our heavy duty locks are built like they've been directly molded on your ball coupler, with 5 to 12 times the mass
of material of universal locks, not to mention the complex built-in mechanism containing multiple discs.
