Hubbell Incorporated OLB-7M conduit 153 cu in LB body

153 cu in LB conduit body

Hubbell Killark OLB-7M is a threaded conduit outlet body built for 2 1/2 in trade-size rigid or intermediate metal conduit. The LB configuration provides a 90-degree directional change in hazardous-location runs rated Class I, Division 2 and Class I, Zone 2. Gray powder-coated iron construction resists corrosion in industrial environments. It suits electricians and facility engineers pulling heavy conductors through tight bends.

142 cu in internal capacity

The body offers 142 cubic inches of usable wiring space, with a 153 cubic inch nominal rating that accommodates large conductor counts and splicing. Threaded hubs accept 2 1/2 in IMC or RMC directly without adapters. Cover model OL-78M seals the access point. The flat back mounts flush to structural surfaces. Capacity is exhausted when fill limits for the conduit size are reached.

Powder-coated iron thermals

Iron construction dissipates heat from high-current conductors without active cooling. No moving parts means silent operation in continuous service. Powder coating adds surface protection but does not alter thermal mass. Power draw is determined solely by the conductors installed; the body itself consumes none. Suitable for ambient temperatures typical of Class I hazardous areas.
