This connector is used to establish a right-angled intersection between two 220-mm ducts. I.e. all 4 arms of the connector are connected to 220mm duct or other components via a: standard joiner (Part No: TC1279-25, Telstra No: 035300515) or a slotless joiner (Part No: TC1279-250A).
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.
