80/20 Inc. 40-4399 Pivot Arm 40 Series Aluminum

Product Description

The 80/20 INC. 40-4399 is an extended straight structural pivot arm designed for use with 40 Series T-slot aluminum framing systems. This external connection component attaches either to a nub or mounts directly to a T-slot profile, making it a versatile fastening solution for structural assemblies. Fabricated from anodized aluminum, it offers a lightweight yet rigid build suited for shelving frameworks and angular structural connections. A set screw is included. The part measures 6.29 inches in length with a width of 1.57 inches and a thickness of 0.25 inches, and it features three mounting holes. Installation is typically performed by industrial builders, fabricators, and trade professionals working with modular aluminum framing systems.

This pivot arm is used in applications where an angled or structured connection between 40 Series aluminum profiles is required. It is commonly specified for shelving assemblies, workstation frames, machine guarding, and similar T-slot modular builds. The external connection method allows the arm to bridge profiles while maintaining a clean structural interface. Use with 40 Series Bolt Kit 75-3422 for a complete fastened assembly. Suitable for both light industrial and commercial modular framing projects.
