Allen-Bradley 1492-EBL3-Y | Yellow End Barrier for 1492-L3 Spring-Clamp Terminal Blocks Lot of 49

The 1492-EBL3-Y is a critical safety accessory designed to seal the exposed "open" side of a terminal block assembly. Because spring-clamp blocks are manufactured with one side open for internal connections, this barrier is required to provide the final insulation at the end of a rail segment. The yellow color is specifically used in industrial panels to warn technicians of potential hazards, such as "foreign voltages" entering the cabinet from an external system.
