Middle Atlantic Internal Elbow - AL3317

Middle Atlantic AL3317 Internal Elbow

Overview

The Middle Atlantic AL3317 is an internal elbow fitting designed to route cables cleanly inside rack enclosures, directing cable runs at a controlled angle to reduce bend-radius stress on conductors and prevent kinking at tight corners. In rack deployments where cable trays meet vertical managers or where horizontal runs must transition to vertical pathways, the AL3317 provides a formed guide point that keeps bundles organized without relying on improvised zip-tie anchors or forced bends. This is a passive hardware component — its value is measured in reduced cable damage over the life of the installation and faster moves-adds-changes when cables are routed predictably.

Compatibility

The AL3317 is designed for use within Middle Atlantic rack enclosures and compatible cable management accessories. It fits installations built around Middle Atlantic's rack infrastructure product line, including enclosed rack cabinets and open-frame racks where internal cable pathway hardware is specified. Confirm interior rail spacing and cable manager channel dimensions against your specific rack model before ordering — Middle Atlantic offers multiple rack widths and depths, and elbow fittings are dimensionally matched to their corresponding tray and manager series.

Installation Notes

Mount the AL3317 at the transition point inside the rack where the cable run changes direction. Secure to the rack structure using the appropriate fasteners for your enclosure model. Maintain manufacturer-recommended minimum bend radii for the cable types being routed — the elbow guides the run but does not enforce a specific radius, so dress cables deliberately and allow adequate slack before the transition point. No special tooling is required beyond standard rack installation hardware.
