Two Different Types of Refrigerated Truck Door Locks

If you're in the business of transporting temperature-sensitive or high-value goods, you already know how important it is to keep your cargo secure. One of the most critical but often overlooked components of that security is your door locks.

Not all truck and semi-truck door locks are the same, especially when it comes to refrigerated trucks. Let's take a look at two popular options: exposed door locking bar systems and hidden door lock bar systems.

Traditional External Locking Bar System

The exposed door locking bar system is probably what comes to mind when you picture the back of a refrigerated truck. These are the heavy-duty steel bars mounted on the outside of the truck doors. They lock in place to physically secure the doors and are known for being strong, reliable, and easy to use.

One big advantage of this setup is visibility it's easy to see if the lock is engaged, and its rugged appearance alone can be a solid deterrent against theft. It's also straightforward to maintain, since all the parts are on the outside and easy to access.

That said, there's a tradeoff. Because everything's out in the open, exposed systems can be more vulnerable to tampering. That's why it's important to invest in high-quality, tamper-resistant truck door locks if you're going with this style.

Sleek and Secure Concealed Locking Bar System
On the flip side, the hidden door lock bar system takes a more low-profile approach. All locking components are hidden within the doors or internal panels of the truck. This design improves security by hiding the locking mechanism.

These systems are great for high-value or sensitive cargo, offering extra peace of mind. Plus, they give your truck a cleaner, sleeker look and are less exposed to the elements.

The only downside is that hidden systems can be a little harder to inspect and service since everything is tucked away. But when security is a top priority, many fleets find the extra protection worth it.
