Overview

The ABB AB221EG Trap-Eze end mount connector is a precision-engineered C-Connector designed for secure anchoring of threaded rods in trapeze systems. Part of ABB’s Trap-Eze series, this end-mount connector is specifically engineered to fit 1-5/8" Superstrut metal channels and accommodate 3/8" or 1/2" threaded rods, providing versatile support for structural and mechanical installations. The SilverGalv finish delivers enhanced corrosion resistance, ensuring long-term durability in demanding industrial, electrical, and construction environments. Key applications include overhead support structures, suspended equipment mounting, and conduit support systems where reliable load distribution is critical. The AB221EG is compatible with Trapnut Strut Fasteners, enabling straightforward installation and adjustment. The connector’s design includes limit bars to ensure proper alignment and prevent misplacement, while the end-mount configuration simplifies assembly in trapeze systems. Installation follows a two-step process: first, secure two Trapnut Strut Fasteners to the threaded rod, then position the AB221EG connector and tighten the fasteners to a snug fit. The strut must be cut 5/8" to 1-1/4" shorter than the center-to-center distance between rods, with ends visible through the connector’s window. The connector supports multiple strut orientations, including open-side facing upward, downward, or sideways, as detailed in installation figures. WARNING: This connector is not designed for cantilevered loads. Strut must always be supported at both ends, and alignment must follow the long side of the connector to prevent structural failure. For trapeze systems requiring center-mount configurations, refer to the AB222EG model. The AB221EG is a critical component in ABB’s installation product line, trusted for its precision and reliability in industrial infrastructure projects.

How to Install the AB221EG C-Connector

This guide provides step-by-step instructions for installing the AB221EG C-Connector onto a threaded rod trapeze system.

Estimated time: 30m

Tools needed:

Screwdriver, Wrench

Supplies needed:

Trapnut® Strut Fasteners, Trap-Eze™ C-Connectors, Strut

  1. Install Trapnut® Strut Fasteners

    Attach two Trapnut® Strut Fasteners to the threaded rod of the trapeze. Ensure they are positioned correctly for the installation of the Trap-Eze™ C-Connector.

  2. Position the C-Connector

    Maneuver the Trap-Eze™ C-Connector onto the threaded rod. Turn the top Trapnut® Strut Fastener downward until it is securely positioned on top of the C-Connector, leaving no more than a 1/2” gap.

  3. Secure the Strut

    Cut the strut to be 5/8” to 1-1/4” shorter than the center-to-center distance between the rods. Place the strut sideways in the Trap-Eze™ C-Connectors to secure the assembly in place.
