There are continuous gaskets that sit between the end caps and body to provide IP66 protection from dust and water. Moreover, the aluminum material provides a degree of EMI/RFI protection.

These electronic enclosures can be used in both free-standing and surface-mounted modes with an optional flange kit. They are aimed at data systems, safety engineering, measurement and control, and networking applications.
