Vertical cable tray connectors

Vertical connectors are specialized fittings that join cable tray sections in vertical runs, allowing safe, adjustable, and code-compliant cable routing between floors or elevations.

Overview

Vertical connectors are essential components in cable tray systems, particularly for multi-story buildings, data centers, and industrial facilities. They provide a secure connection between vertical cable tray sections, ensuring structural integrity, electrical continuity, and proper cable support while accommodating changes in elevation or obstacles.

Types of Vertical Connectors

Vertical Adjustable Connectors

Designed to connect ladder or basket-type trays at varying heights. Allow fine-tuning of alignment to overcome obstacles or elevation changes. Example: I-BEAM Ladder Vertical Adjustable Connector by Atkore, made from lightweight, corrosion-resistant aluminum for easy installation.

Vertical Hinged Splices

Provide flexibility to navigate around pipes, ducts, or other obstructions. Maintain electrical continuity using bonding jumpers. Sold in pairs and suitable for ladder, trough, or channel trays.

Vertical Splice Connectors

Clamp two tray sections together vertically. Include inner ridged plates and outer L-formed plates to support horizontal and vertical alignment. Example: Superior Tray Systems' Vertical Adjustable Splice Connector (SFS-VWB2) for basket trays.

Expansion Joint Splice Plates

Allow limited movement between adjacent tray sections to accommodate thermal expansion or structural shifts. Typically installed with supports near the expansion joint for proper function.

Box and Channel Connectors

Used to terminate ladder or trough trays at switchgear, walls, or concrete floors. Include hardware for secure attachment and maintain alignment.

Materials and Compatibility

Common materials include aluminum, galvanized steel, stainless steel (304/316), and HDGAF steel. Selection depends on environmental conditions, load requirements, and corrosion resistance. Connectors are designed to match specific tray types (ladder, trough, basket, or channel) and widths, ensuring proper fit and support.

Installation Considerations

Secure Mounting: Anchored to walls, floors, or structural steel using heavy-duty brackets. Load Capacity: Must support the weight of cables plus a safety margin for future additions. Electrical Continuity: Use bonding jumpers or oxidation inhibitors where required.

Bend Radius: Ensure cables are not bent beyond their minimum radius to prevent damage. Compliance: Installations should meet NEC and local code requirements for riser and vertical cable pathways. ApplicationsHigh-Rise Buildings: Vertical risers for power and data distribution.

Data Centers: Connecting overhead and underfloor horizontal trays. Industrial Facilities: Routing power and control cables along tall machinery or walls. Telecommunications Hubs: Managing dense fiber optic and coaxial bundles.

Vertical connectors are critical for safe, organized, and scalable cable management, ensuring long-term reliability and compliance in vertical cable tray installations. Proper selection and installation of these connectors reduce labor, prevent cable damage, and maintain system integrity.
