THE EQUIPMENT LOCK COMPANY Heavy Duty Rolling Door - Roll Up Door System - Maximum Security Storage Container , Box Truck & Trailer - Keyed Security - Tough Portable Door - Safety Red

After a break in I had to do something to deter future robberies. This lock gives you the ability to also back it up with a pad lock. Having 2 levels of security has me at ease. Its very easy to use/install and heavy duty.

I used it on a roll up truck door. Works like a charm

I bought this for my cube van rear roll up door. It’s definitely heavy duty. However the part I don’t really like is that, you still need a heavy duty pad lock that can’t be easily cut from bolt cutters. If you have a cheap lock or A lock that can be cut off, you can simply just slide this lock right off the handles. I say this because I tried it. For that reason I gave this product 3 stars. So make sure to buy a heavy duty pad lock if you get this product.

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.

It’s possible to open the door with the lock on, the left side base , is not long enough.
