Cable tray connecting pieces include elbows, T-junctions, 3-way and 4-way junctions, reducers, and joint connectors, available in CAD and modular formats for design and installation.

Types of Cable Tray Connecting Pieces

• Elbows: Used to change the direction of the cable tray horizontally or vertically. Available in 45° and 90° angles .
• T-Junctions and 3-Way Junctions: Allow branching of cable runs into multiple directions .
• 4-Way Junctions / Crosses: Enable cables to split in four directions at a single point .
• Reducers: Connect trays of different widths to maintain continuity in cable routing .
• Joint Connectors: Secure straight sections together, ensuring structural stability .

CAD and 3D Models

• Manufacturer CAD Files: OBO Bettermann provides CAD models for screw connection fittings compatible with software like SOLIDWORKS, Inventor, Creo, CATIA, AutoCAD, and Revit, as well as neutral formats like STEP, STL, IGES, DWG, and DXF .
• Parametric Models: Trimble 3D Warehouse offers parametric cable tray models with configurable junctions, adjustable slopes, corner radii, and hanger placements, suitable for SketchUp .
• Modular Snap-Together Systems: MakerWorld provides modular 3D-printable cable tray systems with T, Y, 90°, and 45° junctions, including Male-to-Male and Female-to-Female connecting pieces for easy assembly .
• GrabCAD Library: Offers a wide range of free CAD designs and 3D models for cable trays and connecting pieces, suitable for engineering and prototyping .

Material and Size Considerations

• Cable tray fittings are typically available in hot-dip galvanized, bare galvanized, or powder-coated steel .
• Heights commonly range from 50mm to 120mm, with widths matching the straight tray sections for seamless integration . These models and fittings allow engineers and installers to customize cable tray layouts, ensure proper cable management, and maintain structural integrity across complex installations.
