There are many types of container locks on the market – but which one should you choose? Here’s an overview of the most popular models and when each of them is the best option.

Container theft is a growing problem at construction sites, warehouses and in transport. Choosing the right container lock depends on both the level of risk and how flexible a solution you need.

Here’s an overview of the most commonly used lock types:

🔒 Removable locks – flexible and mobile

• Mavako Flexlock 1500 (class 5)
  Top-level security, mounted in seconds without tools. Perfect for construction sites where the lock needs to move between several containers.

• Mavako Lock 2550 (class 4)
  A solid mid-range solution. Suitable for areas with medium risk, where good security is needed but not necessarily the absolute top class.

• Ruko RD3641 Padlock (class 3)
  The classic padlock. Best for low-risk areas, short-term storage or as a supplement to other lock systems.

🔒 Fixed locks – maximum strength and permanent protection

• Mavako Lock 3800i (class 5)
  A powerful fixed lock with the highest level of security. Ideal for containers placed permanently in one location.

• Abloy PL 666 (class 5)
  Premium padlock solution with fixed installation. Often used by companies with strict insurance requirements.

• Servial CC Lock 4 (class 5)
  A robust locking system for containers that require maximum resistance against burglary attempts and sabotage.

When should you choose what?

• Low risk (e.g. short-term storage, fenced areas): a class 3 padlock is usually sufficient.

• Medium risk (e.g. smaller construction sites, moderate warehouse activity): a class 4 lock gives a good balance between price and security.

• High risk (e.g. large construction sites, open areas, offshore or transporting valuable equipment): choose a class 5 lock. Here you can opt for a flexible model such as Mavako Flexlock 1500 or a fixed solution like Mavako 3800i or Servial CC Lock 4, depending on whether the container is moved or stays in one place.
