A collection of components for a cable tray system provide the components and basic hardware for assembling and installing a cable tray that can change direction in three dimensions to avoid obstacles or other cables' trays while negotiating a designated space. Components of the cable tray system may be modular, that is, pre-configured for ease of assembly, such as vertical kits and horizontal bend kits, while others are supplied in lengths for cutting them to fit jobsite requirements, such as rails and rungs. Both components provide an inherent framework that facilitates conceptualization and construction of a cable tray system at the jobsite with flexibility and simplicity to allow the present cable tray system to be employed more efficiently and accurately.

A device for the wall-fixing of elongated bodies, in particular radiating coaxial cables, of the type equipped with a spacer provided with a cable clamp equipped with a lid for supporting an elongated body in a suspended position onto a wall. The spacer of the device has a structure composed of two arms, whose end facing the wall is provided with a corresponding base, whereas the opposite end of the arms carries a base for fixing to the cable clamp. With respect to the known wall-fixing devices of radiating coaxial cables, that according to the invention offers the advantage of having an improved resistance to flexural and torsional stress, also preventing interferences with the metallic part of the wall-fixing system.

Each spaced apart support for a cable run in a preferred form includes a hook having a relatively narrower width along the direction of the cable run. A respective extender attached above each hook has a greater length along the cable run than the width of the support in the direction of the cable run, and the extenders thereby provide extended support for cable resting on the extenders along the cable run. Each extender has a slight downward curvature. The opposite ends of each extender have a sharp downward curvature so that the extenders will support resting cable passing over the supports and avoid damage to the cable passing off the extender. A plurality of the supports may be spaced apart at a greater interval such that the longitudinal ends of adjacent extenders are spaced apart defining an acceptable length gap over which the cable run passes.

A wire harness including: a wire harness body that includes an electric wire and an outer sheath configured to cover an outer circumference of the electric wire; a first route regulator that is to be attached to an outer circumference of the outer sheath and is configured to regulate a route of the wire harness body; and a fixing member configured to fix the first route regulator to an attachment target.

A cable management device for mounting to a telecommunications fixture includes an outer barrel disposed over an inner barrel, one of the outer barrel and the inner barrel defining a plurality of discrete detents positioned in a stacked arrangement axially along an length thereof, and the other of the outer barrel and the inner barrel defining at least one flexible cantilever arm defining a tab configured to lock into a selected one of the detents for allowing adjustment of a length of the cable management device.

Methods and devices for reducing stress and for increasing the load-bearing capacity of cable racks supporting electrical power and communication conduits and cables having increased versatility for conduit and cable sizes and quantities. Underground devices including rack arms for these applications are desirably made from plastic or composite materials. Rack arms desirably include openings for tying down the conduits and cables atop the arms. While non-metallic materials are designed to withstand environmental stresses, they typically have strength and rigidity properties less than the metallic structures previously used in such applications. Non-metallic rack arms with such openings may be reinforced locally with a stress attenuator or with ribs to increase their load-bearing and buckling capacity and to reduce their stress, strain and deflection under load. A stress attenuator may be made by increasing the in-molded thickness of the web in areas adjacent to or surrounding the tie-down openings.

A cable management device for mounting to a telecommunications fixture includes an outer barrel disposed over an inner barrel, one of the outer barrel and the inner barrel defining a plurality of discrete detents positioned in a stacked arrangement axially along an length thereof, and the other of the outer barrel and the inner barrel defining at least one flexible cantilever arm defining a tab configured to lock into a selected one of the detents for allowing adjustment of a length of the cable management device.

A cable management frame includes a main body, a bracket installed on the main body, a hook installed on the main body, and a pressing member located on an end of the main body. The hook and the bracket are located respectively on two sides of the main body. The hook includes a reinforcing rib coupled to the main body.

Embodiments described herein comprise a cable system. The cable system has a plurality of cables and a plurality of cable hangers. The cable hangers are configured to support the plurality of cables in a building. The plurality of cable hangers have one or more cable supports configured to hold at least one of the plurality of cables and a support configured to couple the cable support to the building.

A messenger wire hanger includes a body having integral first, middle, and hook portions. The hook portion is in the shape of a hook adapted to hook over a messenger wire. The body defines a first opening between the first portion and the middle portion and a second opening between the middle portion and the hook portion. A lashing strap has a first portion and a second portion with the first portion of the lashing strap being disposed in the first opening of the body and the second portion of the lashing strap being disposed in the second opening of the body. Another configuration uses three openings with a second pawl extending between the second and third openings to define a tortuous path for the lashing strap.
