Middle Atlantic ALA3817N Inverted Internal Elbow
Overview
The Middle Atlantic ALA3817N is an inverted internal elbow fitting designed for structured cable management within Middle Atlantic rack enclosures. It redirects cable runs at an inverted angle inside the rack frame, keeping conductors organized and bend-radius compliant at the point where horizontal or vertical cable managers transition into the enclosure interior. For installers building out AV, security, or IT racks where cable congestion at the manager-to-rack interface creates strain or snagging risk, the ALA3817N solves that specific routing problem without requiring custom fabrication.
Compatibility
The ALA3817N is designed for use with Middle Atlantic rack systems and cable management accessories. It is intended for integration with Middle Atlantic's ALA-series cable management line. Verify fit against your specific Middle Atlantic rack enclosure or open-frame rack model before ordering, as elbow orientation and channel dimensions vary across the ALA product family. Consult the ALA-series compatibility matrix if you are mixing components from different generations of Middle Atlantic cable managers.
Installation Notes
Install the ALA3817N at the transition point where cables exit a horizontal or vertical manager and enter the rack interior. The inverted orientation positions the elbow to guide cables downward or inward depending on the mounting configuration — confirm the correct elbow direction (standard vs. inverted) matches your cable path before installation. No special tooling is required beyond standard rack installation hardware. Maintain minimum bend radius for the cable types being routed; the elbow geometry is fixed, so plan the cable fill before committing.
