A field case housing has an open end, an attachment member and a visual alignment associated with the open end. One visual alignment member option includes a longer elongated visual alignment member and a shorter elongated visual alignment member. Further visual alignment member option is a linear edge of the field case housing. An end plate is adapted to close the open end and has a cooperating visual alignment member formed into a surface of the end plate. The end plate is adapted to align the attachment members together upon visually aligning the alignment members together. An associated method which includes aligning the visual indicia of the field case housing with the visual indicia of the end plate with visual reference thereto and without reference to the plurality of attachment members is also provided.
