    Watertight Knockout Plugs for Enclosures

    Image of Product. Front orientation. Electrical Enclosure Plugs. Watertight Knockout Plugs for Enclosures.
    Don't let water sneak into unused conduit knockouts. These plugs include a gasket that locks out moisture and dust to keep your electrical components dry and contaminant-free.
    Clamp On—These plugs create a tighter hold than snap-in plugs but require access to both the inside and outside of the enclosure to install. Position the two metal plates of the plug on either side of the enclosure wall and tighten to sandwich the wall between them.
    Chemical-Resistant Fiberglass—Won’t break down when exposed to acids, solvents, salt water, and oil. These plugs are also a lightweight alternative to stainless steel.
