Middle Atlantic ALDS4018 External Elbow for ALDS4000 Cable Duct
Overview
The ALDS4018 is an external elbow fitting designed for use with Middle Atlantic's Middle Atlantic ALDS4000 series surface-mount cable duct. External elbows handle direction changes at corners where cable runs transition along the outside of a wall or enclosure edge — keeping conductors protected and routed cleanly without sharp bends that stress cable jackets. In cable management installations for AV racks, access control wiring, and structured cabling in commercial spaces, the right elbow fitting is what separates a professional finish from an exposed, code-questionable run.
Compatibility
The ALDS4018 is engineered to mate with Middle Atlantic ALDS4000 series cable duct components. Confirm your installed duct series and duct width before ordering — Middle Atlantic's ALDS line includes multiple width profiles, and elbow fittings are dimension-specific. Consult the Middle Atlantic rack and cable management accessories lineup to match the correct duct width and fitting type (external vs. internal elbow, flat elbow, T-fitting) for your specific run geometry. This fitting is not a universal elbow — it is designed for the ALDS4000 profile specifically.
