AMPLock's high-security standards
stretch the limits of conventionnal locks.

Engineered with resistance-driven design featuring snug fit for maximized
power of deterrence.

High-grade materials with advanced
mechanical properties offering the best resistance capabilities.

Manufactured with state-of-the-art technologies to ensure long-term reliability.

Experience the level of peace of mind provided by real heavy duty trailer locks.

BUILT TO LAST

SHIELD PART MADE OF
DUCTILE IRON

Massively built and molded according to the specific shape and size of the coupler, the external part absorbs massive and repeated impacts, slow down cutting attemps and resist to high temperatures.

HIGH-GRADE STAINLESS
STEEL BALL LOCK

Provide at once superior hardness,
good corrosion resistance and long-term reliability
. The stainless steel block conforms perfectly your hitch ball dimension.

COMPLEX INTERNAL
MECHANISM

Hard to access for thieves:
Built-in the thickest part of th lock, the mechanism contains multiple discs(1) combined with a rotative face(2) to prevent effectively against picking, tampering and drilling.
Get extra security with dual-part lock series, engineered with swivel design to prevent traction with chains.(3)

E-COAT FINITION AND
HIGH-SECURITY COMPONENTS

The e-coat(1) treatment offers an additionnal protection against dust and corrosion, which means better longevity in tough conditions.
The Shield part thus well-finished, integrates a thick cylinder(2) in its inner shape that slides into the ball lock to strongly sealed the whole structure around the trailer coupler.

"It’s one of the beefiest trailer locks I’ve ever seen. Everything is made of thick solide steel and I think it’s so much stronger than the coupler it secures that making anything beefier would definitely be gilding the lily"

A WHOLE TOOLBOX

CUTTING ATTACKS

Angle grinder, reciprocating saw,
circular saw... AMPLocks slow down all cutting attempt thanks to the hardened materials combination. Selected for their superior mechanical properties for security purpose, for instance the huge amount of resilience provided.

TORCH CUT

The locks structure merges high-density with advanced thermal properties, making them comfortable with hot flush.
It would take thousands of degrees before reaching the melting point of the heavy duty shield and cylinder.

MASSIVE IMPACTS

It could almost hit back!
What better security than a lock that absorbs massive shocks by folding then bumping after impact?

DRILL, LOCK PICKS

40x longer to compromise than
universal locks!

Our trailer locks boast a complex built-in mechanism completed by a rotative face to prevent against drilling.
Moreover, the keyhole is placed to make it difficult to access for thieves and increase the deterrence power.

LIQUID NITROGEN

Meet The locks that whistand the unpredictable!

EXTREME WEATHER

AMPLocks undergo high-quality finition treatments in the final stage to enhance their overall durability.

TLS SERIES

The RV owners choice.

Enjoy the perfect combination of advanced security and convenience.

Boasting a robust monobloc structure, made of ductile cast iron and molded to ensure a tight fit with your coupler, the series provide at once high resistance against cutting and increased deterrence. TLS locks are super easy to operate: after making the structure slide around the ball coupler edges, there’s nothing for it but to push the solid built-in shank to seal your equipment.

Find out the TLS-2 for trailer and RV's hitched with 2" ball, and TLS for 2-5/16" ball coupler, mostly used on AIRSTREAM and JAYCO travel trailers.

Heavy Duty, Extremely Deterrent, Highly Reliable.

Our patented resistance-driven design locks act like
a thick skin of metal surrounding your coupler to provide at once
a tight fit and enough resilience to withstand an entire toolbox.
When the average lock can be easily compromised in seconds,
our dual-part lock will turn all theft attempts into
a long and painful effort.

Wether you operate with 2" or 2-5/16" hitch ball,
BR locks provide custom-fit security solution for all type of coupler:
Each lock has been designed to accurately conform to
the contours of most OEM ball couplers available on the market.
