If you're not sure the lock will fit your coupler - just call them!

I discovered Altor locks after watching the LockPickingLawyer on Youtube. I am very pleased with all 25 pounds of it! The customer service is outstanding. If I get another trailer, then I'll buy another Altor lock.

This is very heavy duty as described, it would probably be easier to cut then weld a new tongue on instead of trying to remove the "ICON"

Nice, hefty, heavy lock. Works like a charm.

Quality product and excellent deterrent.

This BEAST is The Holy Grail of trailer security, nobody makes a better theft deterrent device, NOBODY!!!

They are made well!

Best lock in the business!!

Awesome trailer lock, burly as a tank, and does exactly what it was built for! Thanks for an awesome product!

Excellent service. Answered all my questions. Made sure I had received the keys.

Just let everyone know this is the real deal when it comes to securing your trailer.

The lock is top quality and is a beast of a lock.

Communications and service was the best. I would highly recommend them.

What a solidly built lock. It will definitely not be cut off in a short amount of time. The noise and attention being made in anyone’s attempt would dissuade most dirt bags.
I appreciate the screw-on stainless steel lock protector against the elements. However, It would be nice if it was attached to the lock with some sort of cable. I can foresee being totally absent minded and leaving it on the ground or trailer’s edge while attaching/removing the lock from coupler and than driving off.
Customer service is excellent. AND you’re talking to an actual human!! I had ordered the wrong size for my demco coupler. I called and made arrangements to have it replaced. The lock was replaced quickly.

Have had this lock for nearly 8 years. It’s amazing. Just order a new one for my wife’s new bike. It’s the lightest and most secure lock on the market. I had the previous iteration and accidentally forgot my bike on the street in San Francisco overnight. The next day the bike was still locked. The locked was clearly tried to be Brocken and grinded but they abandoned their effort.

As a beginner RVr, I'm learning SO much. This lock is super simple to use a friend who welds heavy equipment recommended this over others I was considering. It's a bit awkward to carry and store so I ordered the storage bag - it would be wise to make this a part every order.

This lock gives me comfort knowing that my trailer is safe. I know a thief will give up before he steals my stuff. Look no further .

This lock is heavy duty would not hesitate to buy again now I wish Altor made a wheel lock for trailers
