The left adapter, part of the 'PLUS' series of shaped products for sheet cable trays, is used to connect solid and perforated trays of different widths when designing cable routes. The product is designed for transitioning from a metal tray 150 mm wide to a tray 300 mm wide. The element is hot-dip galvanized according to GOST 9.307-2021 and is used for installation in rooms with high humidity and low pollution, outdoors, and in low-corrosive environments, in accordance with GOST 15150-69. To protect the cable route element from external influences and mechanical damage, we recommend using a 'PLUS' series cover for the left adapter, which snaps into place without additional tools.
