Chalfant Manufacturing, a member of the OBO Betermann Group, is a leading provider of high-quality cable tray and cable management systems. Our industry-leading advancements, paired with over 80 years of domestic production experience, sets our products apart.
We supply premium cable trays that are proudly manufactured in the USA in compliance with the Build America Buy America Act, so they qualify for federally funded infrastructure projects.
Chalfant Manufacturing designs and stocks a full range of cable tray systems for electrical contractors and engineers across North America. Our cable trays and cable management systems support and route power, low voltage, and data cabling in manufacturing plants, data centers, warehouses, power facilities, and other demanding industrial environments.
Our aluminum ladder tray revolutionized wire and cable management in manufacturing plants. It remains the industry standard for high-density power and control cable routing across commercial and industrial facilities.
All of our aluminum cable tray systems meet or exceed NEMA VE-1 standards and NEC Article 392 requirements. They are classified by Underwriters Laboratories (UL) as equipment grounding conductors.
The GR-Magic® wire mesh tray system is designed for low voltage and data cabling. Its open construction promotes airflow and gives contractors flexible, accessible routing paths that adapt easily as cabling needs change.
As our flagship cable tray system, GR-Magic® reflects our commitment to innovation. Its patented snap-together connection reduces installation time by 60% to 70%. You do not need screws, plates, or tools to configure this tray.
The BKRS walkable tray is a heavy-duty steel cable tray rated to be walked on, built for power plants, tunnels, and heavy industrial routing where load capacity and access are both priorities.
Every Chalfant cable tray system is backed by a complete line of fittings, bends, covers, and supports, so contractors can build a continuous, code-compliant cable management pathway throughout the installation.
Our team of experts is ready to help you select the right cable tray system and finish for your project. Contact Chalfant Manufacturing today or find your local rep to get started.
| Selection criteria | Aluminum Ladder Tray Long spans, heavy cable | GR-Magic® Wire Mesh Tray Fast, tool-free install | BKRS Walkable Tray Floor-level, step-rated |
|---|---|---|---|
| Best for | Power and control cable runs in industrial, power generation, and oil and gas facilities, including corrosive or caustic environments, indoors or outdoors | Low-voltage and data cabling in data centers, commercial buildings, and warehouses, where routes change often | Cable runs on the floor near machines and robotic production cells, where workers need to step on the tray |
| Material | 6063-T6 aluminum extrusions with 5052-H34 sheet | Steel wire mesh, or aluminum | Steel, with a continuous 2 mm thickness across tray, cover, and barrier strip |
| Finishes | Aluminum, with powder-coated options in standard and custom colors | Electro-galvanized, hot-dip galvanized, aluminum, or stainless steel | Strip-galvanized tray and chequer plate cover; hot-dip galvanized supports |
| Load & span | Support spans up to 40 ft; load rating varies by series and span (see product spec sheets) | Fire-tested to DIN 4102 Part 12 with a 10 lb/ft cable load on 4.9 ft support spacing | Footfall load of at least 350 kg (about 770 lb) per EN 50085-2-2 with the chequer plate cover |
| Mounting & installation | Elevated runs on supports spaced up to 40 ft apart | Snap-together, tool-free connections, with no splice plates or bonding jumpers; mounts directly to walls and ceilings in almost any position | Floor mounting (100–110 mm step height), Z supports, Z-shaped support profiles, or support brackets |
| Key advantage | Lightweight and corrosion-resistant across long spans | Cuts installation time by 60% to 70% | Certified R11 anti-slip and V10 displacement space chequer plate cover; Z-shaped barrier strip separates power, control, and data cables |
| Standards & listings | Classified by UL for use as an equipment grounding conductor | UL Classified; meets NEMA and NEC standards; integrated equipotential bonding | IEC 61537 product standard; barrier strip separation per DIN EN 50174 |
| Sizes | Multiple series and widths (see product pages) | Multiple widths and depths (see product pages) | Six widths from 100 to 600 mm (about 4 to 24 in); 100 mm or 110 mm side heights |
