Cable tray horizontal tees can branch at standard 90° or 45° angles, with specialized angle-type fittings allowing flexible branching for complex layouts.

Standard Horizontal Tee Options

90-Degree Horizontal Tees: These are the most common type, forming a perpendicular branch from a main cable tray run. They are available in perforated or ladder styles, suitable for light to heavy-duty applications, and provide proper cable support and ventilation . Reducing and Expanding Tees: These tees allow the branch width to differ from the main run. A reducing tee has a smaller branch width, while an expanding tee has a larger branch width, enabling smooth integration with different tray sizes . 45-Degree Wye Fittings: For smoother cable transitions and reduced bending stress, horizontal wye fittings provide a 45-degree branch, which is ideal for high-density or sensitive cable installations .

Angle-Type and Custom Tees

Angle-Type Perforated Tees: These specialized fittings allow branching at non-standard angles beyond 90° or 45°, offering flexibility for complex cable tray networks. They feature perforated bases for ventilation and easy cable securing, and often include short straight extensions at connection points for secure splicing . Material and Finish Options: Horizontal tees are available in hot-dip galvanized steel, stainless steel, or powder-coated finishes to meet industrial standards and ensure long-term durability .

Installation Considerations

• Ensure compatibility with the cable tray class (e.g., NEMA Classes 12B, 20A, 20C) and side rail dimensions .
• Maintain proper support and alignment to prevent sagging or excessive stress on cables.
• Use perforated or ventilated designs to allow airflow and prevent heat buildup in high-density installations .
• For custom angles, angle-type tees or wye fittings are recommended to reduce bending stress and maintain cable integrity . By selecting the appropriate horizontal tee—standard, reducing, expanding, or angle-type—you can achieve efficient cable routing at any required angle while ensuring mechanical strength, ventilation, and compliance with industrial standards.
