Pass through plates comprise a body with an opening between opposed first and second surfaces for accommodating the passage of electrical elements. One or more upper retaining elements project outwardly from the body and are positioned adjacent a body top portion. One or more lower retaining elements project from the body and are positioned adjacent a body bottom portion. The upper and lower retaining elements are each configured to both engage respective top and bottom sections of an opening in an external object, and to engage a backside surface of the external object when installed within the opening to retain the pass through plate for attachment with the external object. The upper and lower retaining elements are positioned to enable movement of the pass through plate from an upward position in the opening to a downward position in the opening for fixed attachment with the external object.

A feedthrough for shielding against a radioactive radiation, the feedthrough including: electrical feedthrough conductors; a tubular metal housing including ends and seals, the ends including a respective seals so that an interior is formed in the tubular housing between the seals, the seals including an insulating body through which an electrical feedthrough conductor is fed so that an electrical feedthrough conductor is fixed in the seals while being electrically insulated from the tubular housing; a connecting conductor extending in the interior, the connecting conductor connecting an electrical feedthrough conductor at one of the seals to an electrical feedthrough conductor at another of the seals; and shielding bodies, which are respectively interrupted by at least one opening therein, the shielding bodies being arranged successively in an axial direction of the tubular housing, the connecting conductor being fed through the opening.

An electrical feedthrough includes a base body having a first side and an opposed second side and at least one through-hole extending through the base body from the first side to the second side, an insulating material received in the through-hole, the insulating material having a first surface on the first side of the base body and an opposed second surface on the second side of the base body, and an electrical conductor extending through the insulating material, the electrical conductor having a first diameter at the location of the first surface of the insulating material and a second diameter at the location of the second surface of the insulating material, wherein the first diameter of the electrical conductor is larger than the second diameter of the electrical conductor.

The present disclosure relates to sealing arrangements for sealing locations where cables enter/exit enclosures. The sealing arrangements can include first and second cable sealing modules each including a cable sealing surface. The cable sealing surfaces of the first and second cable sealing modules oppose and contact one another at a cable pass-through sealing interface. The sealing arrangements can be adapted to enhance cable diameter range-taking, sealant conformability, and/or sealant recovery from deformation.

Assembly 18 for securing a bundle of electrical wiring 26 through a roof 12 of a vehicle and a roof rack 10 for supporting a load relative to the roof 12. The roof rack 10 includes an elongate member 14 configured to support the load, one or more mounting mechanisms 16 configured to mount the elongate member 14 to the roof 12, and the assembly 18. The assembly 18 includes a body 20 configured to be placed across a hole 22 defined in the roof 12, the body 20 defining a wiring aperture 24 extending through the body 20, electrical wiring 26 arranged through the wiring aperture 24 and fixed to the body 20, a securing mechanism 28 for releasably securing the body 20 to the roof 12, and a boot 30 configured to cover the body 20, connect to the elongate member 14, and carry the wiring 26 from the body 20 to the elongate member 14.

A grommet assembly includes a wire harness and a grommet including a hollow channel configured to receive the wire harness therein. At least one rib extends inwards from and substantially annularly about the interior surface of the hollow channel. At least one port configured to fluidly couple the hollow channel with an exterior environment is defined by the grommet. Material is injected into the channel through the port to secure the grommet relative to the wire harness. The material injected into the channel flows through interstices located between adjacent wires that define the wire harness so as to encapsulate the wires. The injected material also flows into other voids and openings located within the hollow channel. Upon setting, the injected material is configured to prevent movement of the grommet relative to the wire harness and to prevent the passage of contaminants through the grommet assembly.

A grommet includes: a water stop portion that has an annular shape and is inserted to a through hole formed in an attachment panel for stopping water; and a first partition wall portion and a second partition wall portion that are unit arranged to project toward a radially inner side of the water stop portion. The water stop portion includes: a first contact portion that is capable of coming into contact with a first side surface of a circumference edge portion of the through hole; a second contact portion that is capable of coming into contact with the first side surface; a groove portion formed in an annular shape between the first contact portion and the second contact portion; and a recess/protrusion portion that is formed on a circumferential wall inside the groove portion.

A conduit guide for a concrete beam construction that enables an MEP line to pass through the concrete beam includes a body defining a through passage, a securement panel in the passage, and a pair of sealing flanges on open ends of the body. The securement panel enables securement and/or alignment of an MEP line extending through the passage.
