The 150mm Cable Ladder is a versatile, cost-effective, and open-style cable support system, perfect for managing a wide range of power, data, and control cables in commercial and light to medium industrial applications. Its 6-inch (150mm) internal width provides an optimal balance between ample cable capacity and a compact physical profile. Engineered from hot-dip galvanized steel, aluminum, or pre-galvanized steel, it delivers reliable strength, excellent ventilation, and easy cable accessibility. This system is the go-to solution for creating organized overhead cable routes in office buildings, retail spaces, telecom rooms, and light manufacturing facilities where durability, value, and installation efficiency are key.
The 150mm Cable Ladder forms the backbone of efficient and accessible cable management for countless standard projects. Its classic ladder design—featuring two robust side rails connected by evenly spaced rungs—ensures maximum airflow around cables to prevent heat buildup and simplifies visual inspection and cable laying.
This width is one of the most popular and versatile standards, ideal for routing combined bundles of power, data/communication, and low-voltage cables. It is designed to be lightweight yet strong, supporting the required loads over typical spans (1.5m to 3m) while being easy to handle and install. The system's inherent flexibility allows for straightforward on-site modifications and seamless integration with a full range of bends, tees, and accessories.
Core Advantages:
Optimal Airflow & Heat Dissipation: The open rung design allows heat to escape freely, protecting cable integrity and performance.
Easy Installation & Maintenance: Lightweight for quick handling. Cables can be laid in or tied down from the top at any point, and the open design allows for instant visual tracing.
Proven Durability: Hot-dip galvanized finish provides excellent corrosion resistance for indoor and sheltered outdoor use, ensuring a long service life.
Cost-Effective & Versatile: Offers the perfect blend of performance and value for a vast array of standard applications. Compatible with numerous accessories for system expansion.
Space-Efficient: The 150mm width is sufficient for many cable runs without occupying excessive overhead space, maintaining clean sight lines.
Main Product Styles:
Standard Ladder Tray: The universal choice for most applications, available in Light, Medium, and Heavy Duty load classes to match project requirements.
Ventilated Trough with Ladder Base: Combines the strength of a ladder frame with a perforated or mesh bottom for additional support of smaller cables.
Typical Applications:
Commercial Office Buildings & Retail Complexes
Data & Telecommunications Equipment Rooms
Light Industrial Workshops & Assembly Lines
Educational Institutions & Healthcare Facilities
Power and Lighting Distribution in Warehouses
