Steel enclosure for protecting a Littelfuse RM1000 remote communications monitor from adverse affects of weather and vandalism, while allowing normal communications connections to the RM1000 unit. Its superior design protects an RM1000 from overexposure to UV sunlight as well as from hail during a storm, and it incorporates a seal around the opening in the back to seal the unit to the electrical box, keeping rain from contacting the RM1000 connections. The enclosure also features a built-in padlock tab (padlock not included) to lock the cover to deter vandalism.
