Available in two forms the AT500 Series Connection Box are wall mounted metal connection boxes with backmount frames to accept industry standard IDC strips.

The larger cabinets have standard capacities of 340 pairs (AT510), 680 pairs (AT520) and 1020 pairs (AT530) and are suited for major distribution nodes. Whilst the smaller cabinets with capacities of 100 pairs (AT501), 200 pairs (AT502 and AT 502H) and 400 pairs (AT504), are ideally suited for localised distribution.

Doors are fully lockable and open through a full 180 degrees for ease of access, or can easily be removed and/or reversed.

The AT510/520/530 cabinets can have their capacities increased by replacing the 226 connector brackets (disconnect rails) in the bottom of the boxes with optional expansion kits. These add 50 pairs to each vertical.

Full cable entry and management facilities are included with ample jumper ring provision. Gland plates incorporating 41mm knockouts fitted top and bottom of the box and 80mm knockouts in the sides supply a wide range of cable access possibilities in the larger cabinets, whilst a simple dual glandplate system does the same for the smaller sizes. Alternatively the top and bottom gland plates can be removed entirely.

Lightning protection is fully supported. The backmounts are permanently connected to a 5 way earth terminal.
