A vertical tee, such as the I-BEAM Ladder Vertical Tee Up (VTU), allows cable trays to branch vertically while maintaining secure connections.

Overview

A vertical tee is a cable tray fitting that enables a main cable tray run to split into a vertical branch, either ascending or descending, providing flexibility in routing cables through different elevations . These fittings are designed to complement standard cable tray systems and are available in multiple variations, including ascent, descent, and lateral descent .

Example Products

• I-BEAM Ladder Vertical Tee Up (VTU): Designed for secure NEMA cable tray connections, this fitting is compatible with various NEMA classes and features heavy-duty splice plates for stability .
• Vantrunk Vertical Tees: Available in ascent, descent, and lateral descent configurations, these tees provide flexibility for complex installations .
• AUF409LVTU48 by ABB: A tee fitting suitable for branching cable trays vertically, compatible with standard ladder tray systems .

Compatibility and Classes

Vertical tees are manufactured to match the NEMA class of the cable tray system:

• Class 1: For NEMA 12B and 12C trays, with 1 1/8" wide side rail flanges and 4-hole splice plates .
• Class 2: For NEMA 20A, 20B, and 20C trays, with 2" wide side rail flanges and 4-hole splice plates .
• Class 3: For trays exceeding NEMA 20C, with 2 3/8" wide side rail flanges and 8-hole splice plates .
• Class 4: For heavy-duty systems like 8" high A820E trays, with 2 3/4" wide side rail flanges and 8-hole splice plates .

Key Features

• Provides vertical branching for cable trays.
• Compatible with standard ladder tray fittings.
• Available in multiple orientations to suit installation needs.
• Ensures secure connections with appropriate splice plates and flange widths. Vertical tees are essential for installations requiring changes in elevation while maintaining structural integrity and cable management standards.
