Compared With The Alternatives
| Compared With | How This Product Differs |
|---|---|
| Metal junction box | Metal boxes can rust in outdoor or damp conditions. Plastic is corrosion-resistant and better suited for long-term outdoor use. |
| Non-sealed plastic junction box | A non-sealed box allows water and dust to enter. The MG series has a sealed lid, which provides better protection for exposed wiring. |
| Standard indoor junction box | Indoor boxes are not designed for outdoor exposure. The MG series is built for outdoor and damp environments. |
