Conduit Outlet Body for Hazardous Locations

The Killark OLB-4M is a threaded conduit outlet body built from iron with a powder-coated gray finish. It carries a hazardous-location rating of Class I, Division 2 and Class I, Zone 2 for use with IMC and RMC raceways. The LB-style body provides a 90-degree connection orientation in a compact flat-back design. Electrical contractors specify this fitting for pulling and splicing conductors in demanding industrial environments.

Threaded Hub and Cover Compatibility

A 1 1/4-inch trade-size hub accepts matching conduit and requires the OL-45M cover to seal the opening. The iron construction withstands mechanical stress while the powder coating resists corrosion in damp or chemical atmospheres. With 128.8 cu in of internal volume, the body frees space for larger conductor counts or generous bending radii. The flat back mounts directly against enclosures or structural surfaces without additional brackets.

Upgrade from Standard Bodies

Installers replace standard conduit bodies with this model when hazardous-area approval becomes mandatory. The certified rating eliminates the need for separate explosion-proof enclosures in Class I, Division 2 zones. The jump is worth it whenever code requires documented compliance for flammable-gas atmospheres and the existing fittings lack the appropriate markings.

Questions about this item

How much conductor fill does the 128.8 cu in body allow before reaching code limits?

The 128.8 cu in capacity sets the maximum conductor volume; fill must stay within NEC Chapter 9 limits for the wire sizes used.

Does the powder-coated iron body run hot or create noise when energised continuously?

The iron body is passive with no moving parts or electrical load, so it produces no heat or noise during operation.

Which cover must I already have to close this LB body?

The compatible cover is the OL-45M, which matches the 1 1/4 in trade size and flat-back design.
