"simple plastic box, bit flimsy with nothing inside but a plastic din rail. Box splits into two, the base section having a knockout at top and bottom. Base section fixed to back board with two predrilled holes, one top and one bottom. Likewise top cover fixed to bottom section with two screws diagonally located."
