Swage Ladder - 3-6" Load Depth Hot-Dip Galvanized Ladder Tray

Two hot dip galvanized steel C-Channel profile side rails with transverse ladder rungs; provides the most rigid ladder tray system. Ideal for high vibration environments. C-Channel Swage Ladder trays are prefabricated metal structures that consist of two side rails connected by individual transverse members or rungs. Ladder tray is the most common and the most economical type of tray, also providing maximum ventilation for cabling. Rungs are fastened to the side members by an exclusive swaging process. This method ensures superior mechanical and electrical connection and maximum access to cables even in narrow or divided cable trays. C-Channel Swage Ladder tray systems are a cost effective alternative and allow for easy installation of cables by electricians as well as future access for adding or removing cable runs. All models are UL-classified and meet National Electrical Manufacturers Association (NEMA) VE-1 standards for metal cable tray systems.

  • Universal Curvilinear Splice Plate System The splice plates for rigid connections have a slight curve so they can be used on straight sections or fittings.
  • Tightening of the fastener pulls the plate flush with the side rail. The fasteners are snug and the joint is superior structurally and electrically.
  • Zero Tangent Fittings Tangent as referred to on cable tray fittings is the straight at the end of the curve accommodating a flat splice plate.
  • Zero Tangent Fittings facilitate installation when parallel cable trays must be located at minimum distances from each other, such as motor control centers and switch gear centers. Zero tangent fittings can save up to a minimum of 6" per row of tray.
  • The heart of the Cope design is the tubular rung and its connection to the side rail by cold swaging, a process where special machinery compresses and locks the tubular rung material around both the inside and outside of the cable tray side rails.
  • This connection is made without the use of heat, which can potentially disturb the molecular structure of the metal and weaken it. The tubular rung is flattened during the swaging process to ensure a proper cable bearing surface.
  • Ladder cable trays are the preferred solution and are the most economical choice for creating the ideal routing path.
  • Cold swaging allows for the side rails to be turned outward, simplifying cable installation, and provides 100% access to the cables. The cold swaging yields the most rigid tray system in the industry.
  • The swaged rung connection resists stresses in all directions: up or down, side to side, or in and out. The swaged ladder also resists the camber and warping effects encountered in a typical welded system
  • The increased rigidity means that a 24' section of tray can be lifted on one end with little or no twisting or bending of the tray section. This rigid construction makes the trays safer for field personnel to handle and reduces shipping damage.
