Wire cable tray has proven to be the appropriate solution for cable management in practically every sort of electrical cable installation since its inception. Cablofil, which was first sold in Europe in 1972, is today one of the most well-known names in the wire cable management industry in the United States. The parent firm of Cablofil – Metal Deploye, situated in Montbard, France, patented this unique technology.

Cablofil, Inc. recently proved its commitment to the American market by creating and maintaining a coast-to-coast storage and distribution infrastructure. Cablofil, Inc. sells their wire cable tray from Canada to Brazil, as well as the United States, Mexico, and the Caribbean.

Cablofil’s US production site is in Mascoutah, Illinois, and is within convenient shipping distance of all major urban areas in North America. Cablofil’s US corporate headquarters, production lines, and storage activities are housed at this new complex. The 80,000-square-foot facility’s heart is a technologically sophisticated manufacturing line that produces wire cable tray in various widths.

Cablofil has been delivering effective and cable management solutions all around the world for decades. Cablofil has established itself as a global pioneer in product innovation, quality control, and prompt delivery, with over 50,000 miles of Cablofil cable tray installed globally.

Cablofil is the Solution

Cablofil wire cable tray is a genuinely unique breakthrough in cable management, designed to make installation straightforward and easy. It’s simpler since it has fewer pieces, making installation less difficult. That saves both time and money. A wide selection of attachments allows for virtually any installation option.

Cablofil’s Fast Assembly System (FAS) is the most efficient cable management installation system available worldwide. FAS is a one-step method that does not require any screws, nuts, or other equipment. You only need a screwdriver! From planning through installation, the FAS System helps you to save time and money whether you’re creating a new cable management system or retrofitting an old one.

Cablofil is Easy!

Cablofil is a cable tray idea centered on performance, safety, and economics, three characteristics that make Cablofil the favored cable tray solution among installers. Cablofil wire cable tray adapts to the most complicated arrangements, and its construction provides optimum strength while weighing the least amount. The convenience of designing fittings on-site, as well as the vast selection of unique and universal accessories, allows for total routing freedom and incredibly rapid installation.


In all uses, without specific high loads, the Cablofil wire cable tray structure allows a 6.6′ span between supports.


In the event of an overload, the Cablofil wire cable tray’s mesh structure bends like a hammock yet does not break. The lateral wires are “T” welded to the top edge wires, which reduces the possibility of frayed cables and protects installers from sharp wire ends.

Cablofil's "Safe T Edge" is smooth to protect installers and cable


Installation time is decreased, and no costly prefabricated fittings must be carefully developed or bought. On-site, quick and easy shaping is possible. The only equipment needed to make the most intricate cable lines are a bolt cutter, a screw driver, and a wrench. A diverse assortment of one-of-a-kind supports shortens installation time even further. The tray is so simple to use that a single person can install a system without assistance.

What is Cable Tray?

What is a Cable Tray System?

A cable tray system, according to the National Electrical Code, is “a unit or assembly of units or sections and associated fittings forming a rigid structural system used to securely fasten or support cables and raceways.”

What does this mean?

  • Cable trays support cable the way that roadway bridges support traffic.
  • A bridge is a structure that provides safe passage for traffic across open spans.
  • Cable tray is the bridge that allows for safe transport of wires across open spans.
  • Therefore, think of cable tray as the structural component of a building’s electrical system.

What standards / guidelines are available for cable tray systems?

1. The National Electrical Code is a body that publishes standards for all sorts of electrical applications. Articles 318, 250, and 800 discuss different elements of cable tray systems.

2. NEMA (National Electrical Manufacturers group) is an industry group made up of the major cable tray manufacturers. To far, this committee has issued three documents: NEMA VE1, FG1, and VE2.

NEMA VE1 defines cable trays in general, as well as manufacturing specifications, performance requirements, test standards, and application information. This material is available for free download from the NEMA website.

NEMA FG1 specifies the requirements for fiberglass cable tray systems. This material is available for free download from the NEMA website.

NEMA VE2 is a cable tray installation standard that includes material receiving and unloading, material storage, and general installation standards. This material is available for free download from the NEMA website.

3. CTI (Cable Tray Institute) is a trade group founded by the industry’s key cable tray manufacturers to educate specifiers, designers, and installers with information on the benefits of adopting cable tray systems over alternative types of goods. (For example, conduit, ladder rack, etc.)

What types of Cable Tray are available?

How do I know what type of cable tray is right for my application?

What materials / finishes are available for the various cable tray systems?

1. Steel (Min. Yield = 33KSI) (35 KSI for Stainless)

  1. Plain: hot rolled pickled and oiled steel per ASTM A569 (Commercial Quality) or A570 (Structural Quality)
  2. Pre-Galvanized: mill galvanized steel per ASTM A653 CS (Commercial) or SS (Structural) G90

  2. meet ASTM E-84 smoke density rating; Polyester 680, Vinyl Ester 1025
  3. Class 1 Flame Rating and self-extinguishing requirements of ASTM D-635.

Now that I know what types of cable trays are available, what configurations are available?

1. Straight sections are available to route cables in a horizontal or vertical plane.
2. Fittings are available to route cables in various directions in either the horizontal or vertical planes. Typical examples of fittings include elbows, tees, crosses, and risers. Each of these fittings are available in various radii and bend angles.
3. Covers are accessories and shouldn’t be in here unless splices etc. are included.

After selecting the type of cable tray and configuration required, what support methods are available?

  1. Trapeze Support (Single or Multi-tier)
  2. Hanger rod clamps, “J” hangers
  3. Center Hung Support
  4. Wall Support
  5. Underfloor Support
  6. Pipe stanchions or other structures

In various applications, each of these support techniques is preferred. Trapeze supports, for example, may be required in an application where cables will be dragged through the cable tray. Center hanging supports, on the other hand, are typically employed when cables are to be inserted from the cable tray’s side. Center-hung supports are extremely beneficial for future cable installations. When a ceiling structure is unavailable or undesirable, wall supports and underfloor supports come in handy. The structures available to support the cable tray control outside installations.

What extra information do I need to provide to the cable tray manufacturer before selecting the type of cable tray, cable tray configuration(s), and support method that I want?

Where? Job site and Cable Tray Installation Considerations

1. Outdoor

  1. supports available affect the length and strength requirements
  2.  environmental loads, ice, wind, snow, and possibly seismic
  3. corrosion requirements affect the materials and finishes
  4. classified hazardous locations affect the cable types acceptable

2. Indoor

  1. support locations available affect the length and strength of the system
  2. industrial installation may require a 200 lb. Concentrated Load
  3.  commercial or institutional installation may make system appearance, system weight, and space available important factors
  4.  environmental air handling area may affect cable types, cable tray material, or cable tray type and need for covers
  5.  classified hazardous locations affect the cable types acceptable

What Cable Tray?

1. Type and number of cables to support

  1. NEC cable fill requirements dictate size, width and depth, of system
  2. cable support requirement may control bottom type
  3. largest bending radius of cable controls fitting radius
  4. total of cable weight determines load to support

2. Future requirements

  1. cable entry / exit freedom
  2. design partially full or an expandable system
  3. support type to allow for needs
