The 220 mm duct lid (Part No: TC1279-22SN) is a snap fit onto 220mm straight duct (Part No: TC1279-21). The lid is quickly and easily fitted and removed from 220mm straight duct, when required. Both the lid and duct are made of tough Noryl plastic with a non - halogen fire retardent. The duct connects to other duct sections and various bends, adapters, etc, using either: a standard joiner (Part No: TC1279-25: Telstra S 353/00515) or a slotless joiner (Part No: TC1279250A); which are available separately. A 220mm duct carries up to 800 x 3mm dia optical fibre cords to a depth of 50mm, without causing excessive crushing or stress on them. This is the maximum recommended number of optical fibre cords for 220mm duct.
