Middle Atlantic Ext. Elbow S.s. - S4018

Middle Atlantic S4018 Ext. Elbow Stainless Steel

Overview

The Middle Atlantic S4018 is a stainless steel external elbow fitting designed for rack and enclosure cable pathway installations. This fitting redirects conduit or cable runs at a defined angle outside the rack chassis — useful in deployments where cable must transition from vertical or horizontal pathways to an external feed point without sharp bends that stress conductors or jacket material. The S4018 designation identifies this as a stainless steel variant, suited for environments where corrosion resistance or material matching to adjacent hardware is a factor.

Compatibility

The S4018 is part of Middle Atlantic's rack pathway and enclosure accessory line. It is intended for use with compatible Middle Atlantic rack systems and enclosure families that accept external elbow fittings in this form factor. Verify fitting size and thread or slip specifications against your specific rack accessory configuration before ordering — Middle Atlantic offers multiple elbow sizes and material options across their pathway series, and dimensional compatibility with the mating conduit or raceway section is required for a secure, gap-free installation.

Installation Notes

Stainless steel construction means standard stainless-compatible tools are appropriate — avoid carbon steel hardware in contact with the fitting in humid or corrosive environments to prevent galvanic interaction. Confirm the mating pathway diameter and connection method (slip-fit, threaded, or clamp) match your existing cable management infrastructure. Secure all fasteners to the torque specification of the mating component; over-torquing stainless fittings can gall threads. For installations in network rack enclosures where airflow matters, route cables through the elbow without bundling tightly against active equipment intakes.
