Knockout Seal for 75 mm Conduit

The L.H. DOTTIE KO75 is a carbon steel knockout seal designed to close unused openings in electrical boxes and enclosures. It provides a secure mechanical barrier that maintains the integrity of the enclosure against dust and debris. Electricians and maintenance technicians use it during installations or when reconfiguring circuits in commercial and industrial settings.

Suits standard 75 mm knockout holes in metal boxes

This seal fits the 75 mm knockout diameter commonly found in junction and pull boxes. It is not intended for plastic or non-metallic enclosures that use different retention methods. Buyers who need a seal for a different knockout size or a non-metallic enclosure should look at other options. The carbon steel construction is not rated for corrosive or outdoor environments without additional protection.

Carbon steel construction for 75 mm knockouts

The single specification that determines compatibility is the 75 mm knockout diameter this seal is manufactured to fit. Carbon steel offers high mechanical strength for rigid conduit systems. Verify the knockout diameter of your electrical box matches this dimension before purchase. No other finish or material variant is described in the product data.
