Cable tray tee dimensions diagram

Cable tray tees are represented by their three widths (W1 x W2 x W3) and depth, with options for equal or unequal branches.Tee ConfigurationA cable tray tee is a fitting that allows a branch run to split from a main cable tray line. Tees can be:Equal tees: All three branches have the same width.Unequal tees: The branch width differs from the main run, allowing flexibility in cable routing .Dimension RepresentationThe standard way to represent a tee's dimensions is:W1 x W2 x W3: Where W1 and W2 are the widths of the main and branch runs, and W3 may represent the third branch or depth depending on manufacturer conventions .Depth (D): Often specified separately, indicating the side rail height or tray depth, which affects cable stacking and heat dissipation . For example, a part number like CTUT 25/0300/0150/PG indicates:25: Depth in mm0300: Width of the main run (W1) in mm0150: Width of the branch run (W2) in mmPG: Finish type (pre-galvanized), Material and Finish OptionsCable tray tees are available in:Mild steel (pre-galvanized or hot-dip galvanized)Stainless steel (grade 316L)Covers: Closed or ventilated, depending on cable protection requirements Practical NotesWhen ordering or specifying tees, always indicate whether the tee is equal or unequal.Ensure the widths and depth match the main tray system to maintain structural integrity and proper cable fill.Standard widths typically range from 50 mm to 900 mm, accommodating light, medium, and heavy-duty cable systems . This representation ensures that engineers, contractors, and suppliers can accurately select, manufacture, and install cable tray tees in compliance with project requirements and standards.
