How to mark the tee bends in cable trays

Marking tee bends in cable trays involves precise measurement, clear marking of the bend location, and alignment to ensure accurate T-junction formation.Steps to Mark Tee Bends1. Measure and Plan the Tee Location Before marking, determine the exact point where the tee will branch from the main tray. Measure the distance from a fixed reference point, such as the start of the tray or a wall, to the centerline of the tee. Consider the width of the branch tray and the required angle for proper alignment . 2. Mark the Bend Line Use a marker, chalk, or scribe to draw a clear line across the tray at the measured location. This line represents where the tray will be bent to form the tee. For wire mesh trays, mark the wires that will be cut or bent to create the junction . 3. Indicate the Branch Position Mark the position of the branch tray relative to the main tray. Draw perpendicular lines or reference points to guide the alignment of the branch. This ensures the tee is centered and the branch tray connects at the correct angle . 4. Double-Check Measurements Verify all measurements and markings before cutting or bending. Ensure the bend line and branch position are accurate to avoid misalignment during installation . 5. Safety and Preparation Wear gloves and safety equipment while marking and cutting. Ensure the tray is clean and free of debris to allow precise marking and bending .Tools Commonly UsedMeasuring tape or ruler for accurate distancesMarker, chalk, or scribe for clear linesLevel or square to ensure perpendicular alignmentBolt cutter or cable tray bender for subsequent bending By following these steps, you can accurately mark tee bends in cable trays, ensuring proper alignment and a professional installation. Proper marking reduces errors, minimizes rework, and maintains the structural integrity of the tray system.
