An earth wire holder for a cable tray having two spaced-apart side bars, wherein the earth wire holder is in the form of a spring clamp having a side bar receptacle enclosed by two mounting arms for connecting the spring clamp to the upper edge of a side bar and having an undercut earth wire receptacle enclosed by two holding arms, wherein, when the spring clamp is mounted on the upper edge of the side bar, the mounting arms bear against the side bar under prestress, and the spacing between the holding arms in the section thereof enclosing the earth wire receptacle is smaller than the diameter of the earth wire to be introduced therein.

A support clip can be configured to support objects relative to a cable support system having wire members. A support system engagement portion can have first, second, and third attachments, which can be removably attachable to the wire members of the cable support system. The first attachment can define a first partly cylindrical pocket with a first entrance, the second attachment can define a second partly cylindrical pocket with a second entrance, and the third attachment can define a hook that defines a third elongate pocket and a third entrance. The first and second attachments can be configured to receive respective wire members to attach the support clip to the cable support system in a first orientation and the second and third attachments can be configured to receive respective wire members to attach the support clip to the cable support system in a second orientation.

An object is to provide a technique capable of fixing a plurality of wiring members to the attachment surface as close as possible. A wiring module includes: base member having an attachment surface; a plurality of wiring members disposed on the attachment surface; and a holding member holding the plurality of wiring members in an arranged state on the attachment surface. The holding member includes at least one sheet portion in which at least one hole is formed. The plurality of wiring members are passed through the at least one hole and held in the arranged state. The sheet portion is joined to the attachment surface.

A cable tray assembly comprising a plurality of tray segments, each tray segment comprising a first portion and a second portion positioned about first and second ends, respectively, of the tray segment. The first portion has an inner region between at least sidewalls of the tray segment that is sized to receive placement of a second end of another tray segment. Additionally, the first portion can include one or more open ended grooves that, during assembly of the cable tray assembly, can receive a mating projection that is securely connected to the second end of the other tray segment. The open ended groove can be downwardly sloped, and can extend through an outer edge of the corresponding sidewall. The projection can be fixed or adjoined to the second end at least prior to assembly of the cable tray assembly, and can include shank that is threadingly engaged by a retainer.

A flip-type wire slot relates to the technical field of wire slots, including: a wire slot main body and a wire slot cover, wherein one side of the wire slot cover is fixedly connected to one side of the wire slot main body, the other side of the wire slot cover is a free side, and the free side of the wire slot cover (2) is detachably connected to the other side of the wire slot main body. The adoption of the above technical solution has the advantage of facilitating the removal of the wire slot cover.

In a base member arrangement section, a plurality of wire-like transmission members are divided into at least a first wire-like transmission member bundle and a second wire-like transmission member bundle, and the cover member is fixed to the base member at positions on both sides of the first wire-like transmission member bundle and the second wire-like transmission member bundle and a position between the positions on the both sides to cover the first wire-like transmission member bundle and the second wire-like transmission member bundle. In a non-base member arrangement section, the plurality of wire-like transmission members include a large bundle part where the first wire-like transmission member bundle and the second wire-like transmission member bundle are bundled together.

A duct-bank stub-up assembly includes a first pre-formed stub-up module that comprises a first plurality of conduits and a first encasing body. For each of the first conduits, a first end of the conduit provides a mating end on a mating side of the first encasing body and a second end of the conduit provides a mating end on a top surface of the first encasing body. The assembly further includes a second pre-formed stub-up module that comprises a second plurality of conduits and a second encasing body formed to have a stub-up section and a footer section. For each of the second conduits, a first conduit end provides a mating end on a mating side of the footer section and a second conduit end provides a mating end on a top surface of the stub-up section. The first module is positioned on the footer of the second module.

A wire processing system includes a tray having at least one tray surface configured to sequentially receive a first wire and a second wire from a wire feed system of a wire processing machine. The tray surface has a surface feature configured to provide a wire-to-surface coefficient of friction between the tray surface and the first wire higher than a wire-to-wire coefficient of friction between the first wire and the second wire laying on top of the first wire. The wire-to-surface coefficient of friction reduces movement of at least a portion of the first wire relative to the tray surface during movement of the second wire relative to the first wire.

An assembly can include a barrel housing having an opened end. The barrel housing can also include a barrel port for mounting a first compression fitting. A racetrack tray can be positioned within the barrel housing. The racetrack tray can receive an optical fiber and an electrical cable of a hybrid cable. A cap can be secured to the opened end of the barrel housing. The cap can include a cap port for receiving a second compression fitting. A primary seal can be positioned in a groove on one of the cap or the barrel housing. The primary seal can create a pressure seal between the cap and the barrel housing.

A cable management system may comprise a longitudinal trough with a plurality of lights disposed on an underside of the trough. A power connector may be disposed at an end of the trough communicatively coupled to the plurality of lights. The cable management system may also comprise a second trough or one of a plurality of cable management components, each with a plurality of lights disposed on an underside and a power connector communicatively coupled to the pluralities of lights. The first trough, the second trough, and/or the plurality of cable management components may mate together to form a continuous circuit.
