Abstract: Improved design of cable tray redirector components speeds assembly and connection of cable trays. More efficiently manufactured, universal components needed throughout horizontal redirectors of a specific size and type cable tray run reduce the overall total items and cost of inventory. The improvement is in part the elimination of welding cable redirector components in favor of connecting the components with bolts and nuts in the field. The inventory and shipment of individual parts is substantially more efficient because the new components “nest” efficiently prior to assembly. Moreover, components are designed to minimize the number of bolts and nuts used without jeopardizing strength. The use of bolts and nuts to fasten the components also enables good electrical conductivity for effective electrical grounding of the assembled cable tray system.

Abstract: A cable guide is dimensioned to fit as an insert inside a cable tray. It has a bottom, two sides and a top. The top is made of interleaving, resilient flanges that are spaced apart to define a serpentine path that is wide enough to enable the user to fit a cable into the interior of the cable guide and to remove the cable through the interleaved flanges without disturbing the positional integrity of other cables in the cable tray. The cable guide may be fastened to the cable tray using one or two bolts and may be fastened so that it is spaced apart from the wall of the cable tray. Two cable guides may be installed side-by-side and several can be installed at spaced intervals along a cable tray and throughout a system.

Abstract: 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.

Abstract: A weld-down base conforms to a surface to support other objects, such as cables, motors, water tanks, etc. The base has at least one keyhole shaped hole, with a first portion and a second portion. On the top side of the base, the first portion of each hole is large enough to pass the head of a bolt; the second portion is only large enough to pass the shaft of the bolt but not the head. However, the second portion is stepped near the exit side to be wider so that the bolt head can be inserted into the wider first portion and then slid laterally to the second portion where the step will hold the bolt in place with its threaded shaft extending from the base. The exposed bolt allows objects such as clamps, brackets, signs, lighting, fire extinguishers, hoses, instruments, and so on, to the supporting surface.

Abstract: A cable tray connector that allows for the adjustment of cable trays attached thereto to permit adjustable, angular redirection of the cable tray path within a horizontal plane. Such connector comprises a bed having cable tray attachment zones, where the respective cable trays may be attached; side walls positioned around portions of the bed; and, optionally, a cable guide disposed centrally within the bed. Each cable tray attachment zone may include a first, circular aperture for pivotal attachment of a cable tray and at least one arcuate slotted aperture for adjustable attachment of the same cable tray.

Abstract: An adjustable cable tray joint is provided. The joint has first and second tray receptacles, each having a web and opposing walls. The first tray receptacle may further include joint flanges extending from its walls. The first and second tray receptacles are attached together by pivotal connection, the receptacles defining a rotation relative to each other about the pivotal connection. The joint flanges of the first tray receptacle are disposed proximate to the corresponding walls of the second tray receptacle. The joint includes a locking member extending through a wall of the first tray receptacle and the corresponding wall of the second tray receptacle, the locking member configured to selectively fix and release the rotation between the two tray receptacles.
