Flexible Metal (FMC) Conduit and Fittings

Make tight bends and protect wiring from being crushed. This corrugated conduit snakes around corners where rigid metal conduit won’t fit. For use indoors, it’s ideal for short connections or runs through walls in spaces that require both flexibility and durability.

Conduit

Run wiring through conduit to route and protect it.

Bend and Stay—Flex this conduit and it stays routed in position. It is not designed for repeated bending, which can weaken the construction.

Galvanized Steel—Strong and resists rust and mild chemicals.

Zinc-Plated Steel—The strength of steel with a plating that protects from occasional exposure to moisture.

304 Stainless Steel—The choice for wet and outdoor environments.

Aluminum—One-third the weight of steel that's the same size. Aluminum is also nonmagnetic to prevent electrical interference in nearby equipment.
