- MAXIMUM SECURITY: This heavy duty door lock system is built to secure semi-trailers and sea containers by locking the innermost vertical locking bars together. It features a tamper-resistant tubular pin tumbler lock design for ultimate peace of mind while you’re away.
- COMBINATION SECURITY LOCK: Four-digit combination locks are ideal for multiple users who need to unlock containers or equipment without several sets of keys circulating or getting lost.

Slide the two halves together by inserting the smaller tube into the larger tube. Secure the Cargo Door Lock as tight as possible on both doors' locking arms and depress the locking button with key removed or turn dials.
- HIGH QUALITY: Distinguished by its signature red finish, every lock is protected by a steel-locking structure that can withstand thousands of pounds of force. But it doesn’t stop there! Each device is powder coated before a series of quality assurance checks to ensure security and reliability.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great lock despite it being cut off my conex box!
*by N***. on April 18, 2019*

First off, no matter how much security you put on your box, someone determined to get in will find a way.This may sound odd but I'll be buying this product again despite it having been compromised on my box and all my stuff stolen.I have a security camera and it took the axxhole over an hour to defeat the lock. He didn't try to attack the lock itself but the "arms" on the side of the lock which wrap around the locking bars. It appeared he used some kind of scissor tool (large bolt cutter) and maybe a battery powered angle grinder. Regardless, this little guy put up a hell of a fight and held on until the end.Overall, lock was good and secure. I had it about a year in the rain and sun. Fit and finish was good. No surface rust but a little from inside the sliding portion. When you apply it, be sure to angle it slightly so any water which gets inside drains out.Good product and worth the money. I also had locks on the metal tabs which took almost no time for the guy to cut off.

### ⭐⭐⭐⭐⭐ Heavy duty
