Features and Benefits

- An ultra compact closure for the splicing of optical cables.

- Supplied with 12 single element trays each able to accommodate 12 splices providing a maximum capacity of 144 fibers, or 12 single circuit splice trays. Each single circuit splice tray has two storage sections providing a total of 24 trays per joint. Each tray can accommodate up to 4 splices providing a total capacity of 96 fibers. 

- An input manifold manages the tubes to a common routing channel and has the provision to mount up to four optical splitters.

- The joint is for use with heat shrink splice protectors of either 1.3mm in diameter and 30mm in length or 2.2mm in diameter and 45mm in length. It can also be used with crimp splice protectors.

- The closure base has 4 circular entry ports and an oval port. Cables up to 23mm in diameter can be installed into each port. A further two small ports are available as emergency ports. These ports are for heat shrink entry and can accommodate a cable of up to 12mm in diameter.

- Circular port cables are sealed using a mechanical sealing gland. The gland can be assembled onto the cable away from the joint and is then simply plugged into the base.

- Oval port cables are sealed using adhesive lined heat shrink sleeves or using a mechanical oval port entry kit. See page 3 for more information.

- Multi Way Entry Glands are available to allow the installation of a number of cables into one circular port. See page 3 for more information.

- Splice trays hinge upwards individually, allowing full access to spliced fibers without disturbance to live fibers in adjacent trays.

- Integrated loop storage basket for mid-span applications.

- Can be supplied with a pole/wall mounting bracket.

- Can be supplied with a pressure test valve for flash testing and earthing.
