A conduit layout tool to configured for forming conduit holes or knockouts in electrical boxes or panels. The conduit layout tool can be used with different size strut channel sizes have different widths, height, gauge size and material. The typical width channel sizes are 1⅝ inch and 13/16 inch with (or 7/16 width). A single conduit tool is configured to be used with two or more channel width sizes each with a single conduit diameter.

A protective textile sleeve and method of construction thereof is provided. The sleeve includes a circumferentially continuous wall extending lengthwise along a longitudinal axis between opposite ends. The wall has a first section formed from a non-heat-shrinkable, non-elastic yarn and a second section formed from one of a heat-shrinkable or elastic yarn. The first section extends lengthwise between the opposite ends and spans (X) degrees about the circumference of the wall between opposite lengthwise extending edges while in an unshrunken or stretch. The second section extends lengthwise between the opposite ends and spans (360-X) degrees about the circumference of the wall. The heat-shrikable or elastic yarn of the second section extends continuously as an uninterupted yarn between the opposite edges of the first section.

A woven sleeve for routing and protecting an elongate member includes a wall having opposite edges extending lengthwise in generally parallel relation with a longitudinal central axis between opposite ends. The wall includes warp yarns extending lengthwise between the opposite ends and weft yarns extending circumferentially about the longitudinal central axis. At least some of the weft yarns are provided as bi-component yarns having a central core of heat-set material that biases the opposite edges into overlapping relation with one another, with an outer sheath encircling the central core. The central core and the outer sheath are different colors from one another, such that upon a portion of the outer sheath being split or worn, the central core becomes discernably visible.

Apparatus and associated methods relate to a shapeable conduit. In an illustrative example, the shapeable conduit may have a circumferentially flexible wall extending along a longitudinal axis. The wall may, for example, define a lumen configured to receive one or more cables. Multiple longitudinally extendable manually deformable axial stiffening members may, for example, be circumferentially distributed in the wall. A releasable coupling mechanism may, for example, have at least two mating engagement members. The engagement members may, for example, releasably engage in an enclosed state such that the wall circumscribes the lumen. The engagement members may, for example, be tangentially separable into an open state such that the cables can be radially transferred between an interior and an exterior of the lumen. Various embodiments may advantageously be manipulated such that the axial stiffening members cause the flexible wall to retain cables enclosed within the lumen in a desired configuration.

The present disclosure relates to method for underground installation of a pre-ducted optical fiber cable assembly. The method includes a first step of drilling a first pilot bore from a second manhole to a first manhole. In addition, the method includes a second step of pulling the pre-ducted optical fiber cable assembly. Further, the method includes a third step of drilling a second pilot bore from a third manhole to the second manhole. Furthermore, the method includes a fourth step of pulling the pre-ducted optical fiber cable assembly from the second manhole to the third manhole. Moreover, the method of underground installation of the pre-ducted optical fiber cable assembly eliminates the need for blowing the pre-ducted optical fiber cable assembly with a cable blowing machine.

A system, method, and apparatus for preventing friction based damage to wire conduit comprises a protecting surface configured on or in sections of conduit prone to wire friction as wire is pulled through the conduit.

An object is to further improve the reliability of a bent section of a linear transmission member. Provided is a wiring member including: a linear transmission member that includes a bent section; and a resin molded portion molded with a path holding portion of the linear transmission member being inserted thereinto, the path holding portion including the bent section, wherein recesses are formed so as to expose portions of the path holding portion other than a portion where tensile stress is concentrated due to bending, to the outside.

A method of fabricating a multi-compartment innerduct includes the steps of positioning a plurality of longitudinally extending, laterally spaced, strips of adhesive on a longitudinally extending sheet of fabric material, connecting adjacent of the strips together to form compartments, and attaching the compartments together.

A wiring member includes: a first wire like transmission member; a second wire like transmission member that is more easily bent and deformed than the first wire like transmission member; and a base member to which the first wire like transmission member and the second wire like transmission member are fixed, in which the first wire like transmission member is fixed to the base member through a plurality of first fixing parts, the second wire like transmission member is fixed to the base member through a plurality of second fixing parts, the plurality of first fixing parts are aligned at a first interval in a direction along the first wire like transmission member, and the plurality of second fixing parts are aligned at a second interval smaller than the first interval in a direction along the second wire like transmission member.

A line feedthrough for guiding at least one line through a component, contains a cladding tube, at least one element which is mounted within the cladding tube and can rotate relative to the cladding tube, and a sealing element which is in the form of a flexible hose body and arranged within the cladding tube and the element. The hose body is connected, in an axial end region, to the element and can be displaced by rotational movement between a closed position and an open position. A guide element is provided which can be displaced in the longitudinal direction relative to the cladding tube, and which cooperates with a guide track of the element. The guide track of the element is in a spiral shape, such that a displacement of the guide element in the longitudinal direction leads to a rotation of the element relative to the cladding tube.
