Width of cable tray tee

Cable tray tees are available in equal and unequal sizes, with widths ranging from 50mm to 900mm and depths typically from 50mm to 120mm, depending on the tray type and duty rating.Standard Tee ConfigurationsCable tray tees are designed to connect three cable tray runs, either in equal or unequal widths:Equal tees: All three branches have the same width.Unequal tees: One branch differs in width from the other two, allowing for transitions between different tray sizes . When ordering, sizes are usually specified as W1 x W2 x W3, where W1 and W2 represent the main tray widths and W3 the branch width .Typical DimensionsWidths (W1/W2/W3): 50mm – 900mm for light, medium, and heavy-duty trays .Depths (H): Commonly 50mm, 70mm, 100mm, 120mm, depending on the tray system and load requirements .Rail heights: For ladder trays, 4"–7" (100–180mm) is typical .Radii: Horizontal tees may have radii from 12"–36" (300–900mm) to facilitate smooth cable routing .Material and Finish OptionsMild steel pre-galvanized (PG)Mild steel hot-dip galvanized (HDG)Stainless steel grade 1.4404 (316L) (SS) Covers, either closed or ventilated, are available for all tee types .Selection ConsiderationsCable fill and heat dissipation: Width and depth must accommodate the number and type of cables while allowing airflow .Structural load: Heavier duty trays require deeper or wider tees to support cable weight.Compatibility: Tee sizes should match the straight tray sections to ensure proper fit and alignment . By understanding these dimensions and configurations, engineers and installers can select the correct cable tray tee to ensure safe, code-compliant, and efficient cable routing.
