Enclosure Security Myths

True or False? Metal Enclosures Provide More Security Than Polycarbonate Enclosures.


In fact: twice false.

To explain:

1.) Enclosure security means protecting everything housed by an enclosure from destructive ingress by environmental contaminants including water and dirt.

2.) Enclosure security means protecting everything housed by an enclosure from destructive actions and vandalization by human beings.

In both cases, polycarbonate products provided by AttaBox® Enclosures, deliver the best, proven level of security and protection.

To look further at the “myths” surrounding this issue:


Metal enclosures are stronger than polycarbonate enclosures simply because they are metal.


Security from degradation by environmental elements is directly related to reliable enclosure sealing. The protective capabilities of any enclosure — metallic or polycarbonate — relates to how well the gasket sealing the cover to the body functions. If the gasket fails, the enclosure will fail to protect its contents from ingress of moisture, dust, and other environmental contaminants. Even a small impact on a metallic enclosure can cause enough dimensional degradation to cause a gasket seal to fail. The resilience of dimensional stability offered by polycarbonate enclosures helps ensure that an enclosure can take a beating and continue to provide the protection for which its user paid.


It is much easier for vandals to get into a polycarbonate enclosure vs. a metal enclosure.


The most vulnerable part of enclosure access is the lock, NOT the box, regardless of the material.

Various hinge and latch combinations are available to secure the contents of an enclosure. Although the security requirements will be unique for each application, the selection process should include at least the following considerations:

• Some enclosures are designed with hidden hinges and quarter-turn latches or camlocks with security key access to make these features less prominent and subsequently, less vulnerable.
The foremost consideration is access frequency. Whether an installation must be accessed daily, monthly or annually is very significant. Keeping unauthorized persons out is only slightly more important than ensuring that keys or tools are available when access by authorized personnel is imminently required.

• Will the location or any specifications require a tool for opening?

• Will it require a padlock or other considerations for latches?


In many cases when the enclosure is selected the hinge type is automatically selected because the hinge is an integral part of the enclosure. For some enclosures it is possible to select the hinge or an available hinge-less option.

At AttaBox® Enclosures we specialize in ensuring that you receive the proven security solutions you need. We know that, from simple junction box to central nervous system control of complex processing plants, the contents of enclosures are crucial to the safety of many people. We provide for rigorous security requirements by designing key locations to prevent access by unauthorized or accidental operation of control equipment. Beyond external security measures, direct access to our enclosures can be secured by the choice of hinges and latches and appropriate locking mechanisms.
