Mark 9 copper-free aluminum conduit bodies, covers and gaskets from Eaton's Crouse-Hinds Division are used in conduit systems to act as pull outlets for conductors being installed, provide openings for making splices and taps in conductors, make 90 degree bends in conduit runs, and provide for access to conductors for maintenance and future system changes.

Mark 9 bodies are offered in seven different shapes, and they provide more room for heavier conductors.
