PACLOCK’s TL82A Container Lock

The TL82A Paclock is rated as one of the most secure locks for shipping containers available now.

One major advantage of the Paclock TL82A is that it is made with machined aluminum which is much more secure than a cast aluminum lock because a machined aluminum lock is not vulnerable to being melted or burned by a blowtorch, such as a cast lock is.

This is a keyed lock, one with a 6 PIN cylinder design, so unless somebody has the key to it, they won’t be getting in. Whether someone tries to pick or bump this lock, or just try and open it with pure force, they will be facing a tough time.

To make sure that the Paclock TL82A stays in place when the container doors are open, it comes with a special lanyard to attach it to the doors of the shipping container.

It is also worth noting that the lock is made in the USA. This may not be a cheap lock for a shipping container, but considering how secure it is, it is well worth the investment.

• Resistant to melting
• Resistant to impact and picking
• Made in the USA
