About Conduit

Compare rigid and flexible conduit materials and identify the trade size for compatible fittings.

Conduit Locknuts

Secure threaded conduit fittings to knockouts. These locknuts keep fittings from shifting, so connections stay stable and wiring is protected inside electrical boxes or enclosures.

Facing

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.

316 Stainless Steel—Our most corrosion-resistant fittings won't degrade when exposed to salt water and harsh chemicals.

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

Nickel-Plated Brass—The plating enhances the corrosion resistance of brass, adding a durable protective finish.

PVC Molded Gasket—Creates a seal for moisture protection.

Serrated Facing—Grips the material surface for added stability.

Conduit Locknut and Reaming Pliers

Tighten locknuts and ream both the inside and outside of conduit with one tool. These pliers have combination jaws with multiple curved openings to work with _1/2" (13 mm) and _3/4" (19 mm) EMT conduit locknuts and _1/2" rigid conduit locknuts and flat nuts. Their machined nose fits snugly into locknut wings. They can also pull wire and fish tape, thanks to their serrated jaws. Pliers have plastic grips for comfort.
