Killark OL-10M Conduit Body Cover 1/2 in video accessory

Conduit body cover for 1/2 in hubs

The Killark OL-10M is a silver steel cover designed for Hubbell Killark malleable iron conduit bodies with a 1/2 in hub. It carries CSA LR11852 and UL E3397 listings and is rated for Class I Division 2 hazardous locations. The O Series accessory includes mounting screws and suits electrical installers who need a compliant enclosure seal.

Screw-in installation with no gasket

The cover fastens by screwing directly onto the conduit body threads, requiring only a screwdriver and the supplied hardware. Because no gasket is included, the joint relies on thread engagement alone; installers must ensure threads are clean and undamaged to maintain the hazardous-location rating. Overtightening can strip the malleable iron threads and compromise the seal.

Verify hub size and hazardous rating

Before ordering, confirm the conduit body has a 1/2 in hub and belongs to the Killark O Series malleable iron range. The cover is approved only for Class I Division 2 areas; it must not be used where a higher division or different class rating is required. Cross-reference the CSA LR11852 and UL E3397 markings on the existing body to match the cover certifications.
