This 50-mm duct is similar to the standard duct except that it is slotted to allow fibre feed off at any point and external vision of the “ducts” contents. It carries up to 280 pigtails or patch cords (Ø2mm dia.) to a depth of 30mm without excess stress on them during removal. The duct comes complete with a full length extruded lid, and is made of tough Noryl plastic with a non-halogen fire retardant. It connects to other 50mm duct sections and various bends, adapters etc., using joiner (Part No: TC1279-73). It is recommended that each outlet slot be fitted with an outlet radius guide (Part No: TC1279-212KIT – x 10 in a pack), that will guarantee the outgoing radius for every housed optical fibre cord. These are available separately.
