Cable Tray Tee Specifications and Dimensions Table

Cable tray tees are standardized fittings with widths, heights, and depths matching the main tray sections, typically ranging from 50 mm to 120 mm in height and 100 mm to 600 mm in width.Standard Cable Tray Tee DimensionsCable tray tees are designed to branch cable runs at right angles while maintaining compatibility with straight tray sections. The key dimensions include width (W), height (H), and depth (D), which are generally aligned with the main tray specifications to ensure structural integrity and proper cable support .Width (W)Height (H)Depth (D)Material ThicknessNotes100 mm50 mm1.2 mmMild steel / GalvanizedSuitable for light cable loads150 mm70 mm1.5 mmMild steel / Epoxy coatedCommon in commercial installations200 mm100 mm1.5 mmHot-dip galvanizedSupports medium cable bundles300 mm120 mm2.0 mmMild steel / GalvanizedIndustrial or high-density applications400 mm120 mm2.0 mmHot-dip galvanizedHeavy-duty power or data cables500 mm120 mm2.0 mmMild steel / Epoxy coatedLarge cable runs in data centers600 mm120 mm2.0 mmHot-dip galvanizedMaximum standard width for most industrial traysAdditional ConsiderationsRung Spacing: For ladder-type trays, standard rung spacing is typically 150 mm, 225 mm, or 300 mm, depending on cable type and load .Tray Length Compatibility: Tee fittings are designed to match standard straight tray lengths of 3 m, 6 m, 9.1 m, or 12.2 m .Material and Finish: Options include mild steel, hot-dip galvanized, or epoxy powder-coated steel to resist corrosion and meet environmental requirements .Code Compliance: Dimensions follow NEC, NEMA, and IEC standards to ensure proper cable fill, heat dissipation, and structural safety . Cable tray tees are selected based on the width of the main run and the branch, ensuring that the height and depth remain consistent to maintain cable support and prevent overcrowding. Proper sizing also facilitates future expansion and inspection compliance.
