Product identity

The APC AR7755 is an overhead cable extension kit built for vertical exhaust ducts on SX enclosures. It targets data-centre operators who need to route cabling above a 600 mm wide duct while preserving the intended airflow path.

Installation prerequisites

Confirm that the target enclosure is an SX model with a vertical exhaust duct measuring 24 inches across. Verify that the overhead space above the duct can accommodate the extension without interfering with cable trays, busways or fire-suppression hardware already mounted in the aisle.

Bundled impact

The kit supplies the structural pieces required to extend the duct vertically, letting cables pass overhead without blocking hot-air ejection. This arrangement keeps thermal performance consistent while freeing valuable rack-side room for additional patch panels or power distribution units.

Questions about this item

What is included in the AR7755 kit and what must be purchased separately?

The kit contains the overhead cable extension and vertical exhaust duct components for a 600 mm wide SX enclosure; the SX enclosure itself and any mounting hardware are sold separately.

Which width version should I select for a 600 mm wide SX enclosure?

Choose the 600 mm wide version, also described as 24 in wide, which matches the stated enclosure width.

How does the 600 mm wide duct affect airflow once installed in the enclosure?

It extends the vertical exhaust path upward, directing hot air overhead and away from the 600 mm wide SX enclosure to improve thermal management.
