The entry suite is basically a 220mm vertical drop off point in a 300mm horizontal duct system. This is usually installed where a large number of optical fibre cords are to be dropped off below: eg. in optical fibre distribution frames. It provides free flow for the ongoing fibres and strain relief for those exiting down the 220mm vertical section. There are two 300mm horizontal outlets, which use slotless joiners (Part No: TC1279-287A) and a 220mm vertical outlet that uses a slotless joiner (Part No: TC1279-250A). Joiners: available separately.
