Nonmetallic enclosures contain electrical components and provide protection from damage and moisture. These enclosures also provide UV, corrosion, and chemical resistance, which makes them ideal for outdoor applications in environments exposed to sun or rain.

Shielded metallic boxes protect electronic devices from outside disturbance and are commonly used to reduce the electromagnetic interference (EMI) and radio frequency interference (RFI) that can be caused by cell phones, power lines, lightning, and solar flares.
