Cable tray single-sided tee specifications and dimensions

Single-sided tee cable trays are available in equal or unequal widths, constructed from steel or aluminum, and designed to meet NEMA/CSA load ratings with a 1.5 safety factor.General Description

A single-sided tee is a cable tray fitting that allows a branch to diverge from a main tray run at a 90° angle. These tees can be equal or unequal, depending on the widths of the main and branch trays, and are typically specified using the format W1 x W2 x W3, where W1, W2, and W3 represent the widths of the main run and branch sections .

Material and Construction
  • Materials: Steel (hot-dip galvanized, stainless, or painted) or aluminum .
  • Side Rails: Extruded I-beam or fabricated steel/aluminum, nominal heights typically 4–8 inches .
  • Bottom Type: Ladder, ventilated, solid, or channel, depending on cable support and ventilation requirements .
  • Rungs/Supports: Spaced to allow proper cable support, often 12 inches center-to-center for ladder types .
  • Finish: Smooth edges and welds to prevent cable damage; zinc or epoxy coatings for corrosion resistance .
Load Ratings
  • Safety Factor: 1.5 applied to all tray sections .
  • Concentrated Load: Supports an additional 200 lb on any portion of the tray beyond published load class .
  • Span Deflection: Deflection measured at midpoint; continuous spans may reduce deflection by up to 50% .
Standards and Compliance
  • NEMA VE 1: Metallic cable tray systems .
  • CSA Load Classes: C/3M or as specified for the project .
  • ASTM Standards: A123, A653, A1011, A1008, B633 for steel and coating specifications .
  • Electrical Codes: ANSI/NFPA 70 (NEC) compliance .
Ordering Information
  • Specify widths (W1 x W2 x W3) and material.
  • Indicate tray type (ladder, solid, ventilated) and finish.
  • Include load class and any special requirements for branch angles or radius .
Installation Notes
  • Use splice plates or connectors provided with each fitting for secure attachment .
  • Ensure proper grounding and electrical continuity according to NEC and manufacturer guidelines .
  • Verify that the tee aligns with the main tray run and supports the intended cable load without exceeding deflection limits . This specification ensures that single-sided tee cable trays are mechanically robust, electrically safe, and compatible with standard cable management systems.
