Seals are used to cover up exposed knock-out holes in steel boxes and other metal enclosures. They are suitable for indoor and outdoor use. The seals are made with zinc-plated steel for strength. The covers expose the knock-out holes. They have corrosion-resistant zinc-plated steel construction.

Conduit Seals
Conduit Seals are installed in conduit runs to prevent the passage of gases, vapors, or flames from one portion of the electrical installation to another through the conduit, limiting any explosion to the enclosure and preventing pre-compression or “pressure piling.”

Steel Seals have easy and fast installation and use factory assembled components. There is a high degree of flexibility with interchangeable sealing block assemblies and selection of different sizes of frames.
