The element is part of a system for constructing cable routes of any complexity at industrial, civil, and commercial facilities. The T-junction is designed to create a branch in the cable route, while rotating the open part of the tray around its axis by 90 degrees. The kit includes a section cover that protects the laid cable from mechanical damage, dust, and debris. The element is hot-dip galvanized according to GOST 9.307-2021 and is used for installation in high-humidity and low-pollution indoor environments, outdoors, and in low-corrosive environments, in accordance with GOST 15150-69. The product is used to organize a smooth turn and transition of the route from an initial tray width of 500 mm to a width of 150 mm. The shaped section prevents cable damage during installation and allows for rational use of the internal volume.
