Final answer:
A coupled bend consists of two 90° bends fabricated on the same length of conduit. It is commonly used in electrical installations to change the direction of a conduit without using additional fittings.
Step-by-step explanation:
The type of bend that consists of two 90° bends fabricated on the same length of conduit is called a coupled bend. It is commonly used in electrical installations to change the direction of a conduit without using additional fittings. In a coupled bend, the two 90° bends are aligned or anti-aligned, meaning they either point in the same direction or opposite directions.
