Middle Atlantic ALA4817N Inverted Interior Elbow
Overview
The Middle Atlantic ALA4817N is an inverted interior elbow accessory designed for structured cable routing inside Middle Atlantic rack enclosures. Interior elbows redirect cable runs at a controlled angle within the rack cavity — keeping bundles off sharp edges, maintaining bend-radius compliance for fiber and Cat6A, and allowing clean dressing along the vertical manager path. The inverted orientation addresses installations where cables enter or exit from below, routing upward through the manager column without sharp 90-degree stress points. The ALA4817N designation places this in the ALA (Adjustable Lacing Arm / elbow accessory) series within the Middle Atlantic rack and enclosure accessory line.
Compatibility
This elbow is engineered for use within Middle Atlantic rack enclosure systems that use the standard vertical cable manager framework. Verify interior clearance dimensions against your specific Middle Atlantic rack model before ordering — elbow fittings are sized to the manager column width and the rack's internal bay depth. Consult Middle Atlantic's rack cable management accessories selector or your rack's bill of materials to confirm the ALA4817N matches your manager configuration. If your installation requires a non-inverted elbow or a different radius, Middle Atlantic offers companion elbow variants within the same ALA family.
Installation Notes
Interior elbows clip or fasten into the vertical manager channel — confirm the attachment method (snap-fit versus screw-mount) matches your manager column before installation. Maintain minimum bend radius per cable type: 1 inch for Cat6A UTP, 4× cable diameter for fiber patch. Do not over-bundle — cables compressed through an elbow exceed bend-radius limits even when the elbow itself is correctly installed. Route heavier copper runs first, then patch fiber over the top. For structured cabling planning in high-density rack builds, pair this elbow with a horizontal lacing bar to anchor the redirected bundle before it transitions to the equipment shelf.
