Heavy Duty Rolling Door Lock - Maximum Security for Storage Container, Trailer, or Box Truck Lock - Keyed Roll Up Door Security (Keyed Differently)

Used this on a U-Haul truck and it worked fine. Using this device does not interfere with using a padlock on the normal door locking mechanism so we used both. I felt it provided a significant additional level of security beyond the padlock but, of course. thieves probably can defeat it although I suspect it might be simpler to just be cutting into the truck wall if one wanted to be so determined to steal from the truck.

I am an engineer, so I go overboard on things at times because I want more than the very best and I want more security than usual, especially for this move in a 26' Uhaul truck. I bought this FOR 1 MOVING TRIP FROM FLORIDA TO TEXAS FEBRUARY 2021. I was carrying all of my belongings which included a load of firearms, a mountain of ammunition, and a lot of precious metals that I wont mention here, but enough that I could not carry them into the hotel at night.I bought it brand new and was skeptical at first, but after installing it, I knew NO ONE could break into my Uhaul while traveling 3 days and nights staying at hotels. This lock is ultra heavy duty, solid and will not break - PERIOD! The truck will break first and in fact, the entire truck could be obliterated and the only thing left still working would be this lock. It is that heavy duty. It will last a lifetime if you need one permanently and travel with important items. Fits all Uhaul Trucks as they have WHITING Brand Door Hardware. Also fits all TODCO Brand Door Hardware.

I used it on the roll up door on the UHaul I was using when I moved. It installed very easily and fit nicely. I am not sure if it prevented anything, but the truck never got broken into. No lock is undefeatable, but this one would add a lot of time and difficulty to anyone trying to break in. Worth the money even if it prevents one break in.

Had a lock cut off and thousands of dollars ($60k+) of tools stolen by scumbags!They did it while the alarm was going off!No lock is perfect, but, it's going to take a lot of time and noise to break-in now.Whish I had purchased this prior to losing so much. I even knew about it, but kept putting it off! 🤬Don't be like me, if your looking at this you obviously need it!

I used this product to make sure that my 14' box truck and the contents inside were secure. And I was able to leave the paddle lock in place as well! There is absolutely no doubt, that if someone wanted to steal what is inside, it would be almost impossible, I love it! Easy to use, very heavy duty!

Kept getting my truck broken into hope this helps .

Cross-country trip, stopping in some cities that I needed to leave the truck parked on the street for a couple of nights, (while renting a car to play tourist), and felt very comfortable and confident doing so. No problems what-so-ever. Easy to use. When stopping for gas at truck stops, we had a number of semi drivers come over to look at it. They all put their stamp of approval on it.

The supplied key did not work. Made it useless when I tried to use it on my moving trip. Unacceptable to have that low of QC for such a simple product.
