100 cable tray converted to a tee

A 100mm cable tray can be connected to a tee using an equal or medium-duty tee fitting, available in galvanised steel or stainless steel, with integral couplers for easy installation.Types of Tees for 100mm Cable TraysEqual Tee: Branches the tray into two equal 100mm sections, ideal for symmetrical layouts (Metsec CTET25/0100HDG) .Medium Duty Flat Tee: Designed for 100mm trays with integral coupling tabs and fishplates, eliminating the need for separate couplers .Stainless Steel Tee: Suitable for light-duty applications where corrosion resistance is required, such as Legrand SST100S .Material and Finish OptionsMild Steel Pre-Galvanised (PG): Standard for most indoor installations .Hot-Dip Galvanised (HDG): Provides extra corrosion protection, suitable for outdoor or humid environments .Stainless Steel 316L (SS): High corrosion resistance for harsh environments .Installation ConsiderationsTees often come with integral couplers or fishplates, simplifying alignment and reducing installation time .Ensure the tee matches the tray width and depth (100mm in this case) for proper fit.Ventilated or solid covers can be added depending on cable protection requirements .For custom layouts, unequal tees or adjustable bends may be used to accommodate different branch widths .Ordering and Part NumbersExample: Metsec part number CTET25/0100HDG indicates a 100mm equal tee in hot-dip galvanised finish .Part numbers typically encode depth, width, and finish, which helps ensure compatibility with your existing tray system . By selecting the appropriate tee type and material, a 100mm cable tray can be efficiently converted into a branching configuration while maintaining structural integrity and ease of installation.
