Killark OL-450 Conduit Body Cover 1-1/4 and 1-1/2 in

Conduit Cover for 1-1/4 and 1-1/2 in Hubs

The Killark OL-450 is an aluminium cover designed to seal conduit access fittings in hazardous locations. It fits Hubbell Killark copper-free aluminium conduit bodies with 1-1/4 in or 1-1/2 in hub sizes. The screw-in connection includes mounting screws for secure attachment. Rated for Class I, Division 2 environments, it meets CSA LR11852 and UL E3397 standards for industrial safety compliance.

Replaces Damaged or Missing O-Series Covers

This cover restores the protective seal on existing O-Series conduit bodies where the original lid is lost or corroded. The upgrade is worth it when an inspection requires a compliant cover with the correct hazardous-location rating. Silver aluminium construction matches the existing fitting material to maintain galvanic compatibility. The 0.1 lb weight adds negligible load to the conduit run.

Verify Hub Size and Hazardous Rating Before Ordering

Confirm the conduit body hub measures exactly 1-1/4 in or 1-1/2 in to match the cover dimensions. Ensure the installation site requires a Class I, Division 2 rating, as this cover carries no gasket and is not rated for other hazardous classes. Check that the O-Series mounting pattern aligns with the included screws. Buyers needing a gasketed seal or a different hub diameter cannot use this cover.
