Slanted tee on the back of the cable tray

A slanted tee on a cable tray is a side-fitting that allows cables to branch off at an angle from the main tray, typically achieved using unequal or angled tees.OverviewA slanted tee is a type of cable tray fitting designed to connect a branch tray to the side of a main cable tray at an angle rather than perpendicularly. This allows for flexible routing of cables in complex installations, especially when space constraints or directional changes are required. These fittings are commonly used in light, medium, and heavy-duty cable tray systems with widths ranging from 50mm to 900mm .Types and ConfigurationsEqual Tees: Both branch and main tray widths are the same, typically used for symmetrical branching .Unequal Tees: The branch tray width differs from the main tray, which can create a slanted or angled connection when installed at a non-perpendicular orientation .Horizontal vs Vertical Tees: Horizontal tees maintain the same plane as the main tray, while vertical tees allow branching in a different plane, which can also be used to achieve angled routing .Materials and FinishesSlanted tees are available in various materials to suit environmental and load requirements:Mild steel pre-galvanized (PG)Mild steel hot-dip galvanized (HDG)Stainless steel grade 1.4404 (316L) (SS) Covers, either closed or ventilated, can be added to protect cables from dust or mechanical damage.Installation ConsiderationsEnsure the tee is properly supported to handle the weight of the branch tray and cables.Follow BS EN 61537 and BS 6946 standards for safe installation and load handling .Use equal or unequal tees depending on the required branch width and angle. Unequal tees are often preferred for slanted connections.Maintain proper alignment and secure the fitting to prevent cable strain or misalignment.Practical ApplicationsSlanted tees are particularly useful in:Routing cables around obstacles or structural elements.Connecting branch trays at non-90° angles for optimized cable management.Industrial or commercial installations where multiple cable paths converge.By selecting the appropriate unequal or angled tee and following installation standards, a slanted side connection can be safely and efficiently implemented in a cable tray system .
