  • Patent number: 9578765
    Abstract: A fiberglass hole plug for sealing unused openings in electrical enclosures is disclosed. The hole plug includes a cover having a first side and a second side and defining a peripheral edge and a threaded member having a first end and a second end. The second end of the threaded member is attached to the second side of the cover, axially extends in a direction away from the cover, wherein a radial distance between the threaded member and the peripheral edge on the second side of said cover is less than or equal to one-half inch. The hole plug further includes a fastener threadably attached to the threaded member, whereby rotation of the fastener adjusts a longitudinal distance between the first end and the second end of the threaded member.

  • Patent number: 5843532
    Abstract: A method of coating a conduit outlet fitting is disclosed. In the method, a tooling plate is positioned between a cover and a body of the conduit outlet fitting. The tooling plate has a hanger tooling block and a plug tooling block affixed thereto and positioned inside the body when the tooling plate is positioned between the body and the cover. A hanger is passed through a conduit opening and attached to the hanger tooling block. A plug is passed through another conduit opening and attached to the plug tooling block. The hanger and the plug each have a cap disposed thereon for covering an external end of their respective conduit openings. The assembled structure is suspended from the hanger and dipped into a liquid protective coating material to form an external coating thereon. The cover, the body and the tooling plate cooperate to form complementary male and female seals on the cover and the body. The dip coated structure is removed from the coating material and cured.
