This connector is used to establish a right-angled intersection between two 100 x 50mm ducts. i.e. all 4 arms of the connector are connected to 100 x 50mm duct or other components using joiner (Part No: TC1279-226).
NOTE: Care should be taken not to lay more than 50mm depth of pigtails or patch cords in troughing, particularly where they cross each other at right angles. This may occur with this connector.
