ABSTRACT:
A modular structure for attachment to a rail includes securement members received and supported on either side of the rail. The rail includes a support web and parallel side flanges. The structure is constructed from a molded plastic base unit to which metallic securement members are assembled. The base unit preferably includes a rigid side and a flexible side. The securement members are substantially identical to one another, facilitating manufacturing and assembly, and reducing the number of different parts in the final module. The securement members each include v-shaped slots for engaging the side flanges of the rail. The base unit may be configured as a blank end unit, or may include features for creating terminal blocks, I/O blocks, switches, circuit board supports and the like.
