Various irregular-shaped horizontal tees for cable trays

Horizontal tees for cable trays come in standard, reducing, and expanding configurations, with options for light, medium, and heavy-duty systems in various materials and finishes.

Types of Horizontal Tees

Standard Tee: All three branches have equal widths, ideal for symmetrical cable routing. Reducing Tee: One branch is narrower than the main run, allowing transition to smaller cable trays. Expanding Tee: One branch is wider than the main run, suitable for merging into larger cable trays.

Irregular or Custom Tees: Some manufacturers offer tees with non-standard angles or dimensions to accommodate complex routing or space constraints.

Duty Levels and Compatibility

Light, Medium, and Heavy Duty: Horizontal tees are available for all duty levels, supporting cable tray widths from 50mm to 900mm.

NEM

A Classes: Class 1 (12B, 12C), Class 2 (20A, 20B, 20C), and Class 3 (exceeding 20C) are supported, with corresponding side rail flange widths and splice plate configurations.

Materials and Finishes

Mild Steel: Pre-galvanized (PG) or hot-dip galvanized (HDG) for corrosion resistance. Stainless Steel: Grade 1. 4404 (316L) for high corrosion environments.

Special Coatings: Some suppliers offer brushed or polished finishes for aesthetic or sanitary applications.

Additional Features

Closed or Ventilated Covers: Available for all tees to protect cables or allow heat dissipation. Custom Dimensions: Heights typically range from 50mm to 120mm, with widths adjustable to match straight tray sections.

Clean

Tray Options: Designed for frequent washdown areas, with right-angle 90-degree tees in stainless steel.

Selection Considerations

When choosing irregular-shaped horizontal tees, consider: Cable load and tray width: Ensure the tee matches the main and branch tray widths. Material and finish: Match environmental conditions (indoor, outdoor, corrosive, or sanitary). Duty level: Light, medium, or heavy-duty depending on cable weight.

Custom requirements: Non-standard angles or branch widths may require manufacturer consultation for custom fabrication. These options allow flexible cable routing in complex installations while maintaining structural integrity and compliance with industry standards.
