Anchor Cable Cross Arm - 4 ft

Anchor Cable Cross Arm 4 ft – ANSI Z359.18-2017 Compliant I-Beam Cable Anchorage Strap

The Anchor Cable Cross Arm (Part #AC48408) is a 4-foot, 5/16" (8mm) vinyl coated I-beam cable cross-over strap designed for use as a temporary or permanent anchorage connector on structural steel and I-beam applications. Built from PVC coated galvanized steel cable with forged steel O-rings, it is engineered for fall protection systems used by construction and trades professionals working at height. The strap features one large forged O-ring on one end and a smaller forged O-ring on the other for pass-through rigging configurations. It meets or exceeds ANSI Z359.18-2017 Type T standards, making it a code-compliant anchorage solution for regulated job sites.

Technical Specifications

Available Sizes

Unlike web strap anchorage connectors, this cable cross arm uses galvanized steel wire rope with a PVC vinyl coating, providing superior abrasion resistance and durability in harsh job site environments. The dual forged O-ring configuration — one large, one small — enables versatile pass-through rigging without additional hardware. Its compliance with ANSI Z359.18-2017 Type T ensures it meets the same standard required for engineered anchorage connectors on regulated construction sites.

Key Features & Benefits

ANSI Z359.18-2017 Type T Compliance

This cable cross arm meets or exceeds ANSI Z359.18-2017 Type T, the recognized standard for anchorage connectors used in personal fall arrest systems. Compliance gives contractors confidence that the product satisfies OSHA-referenced industry standards for fall protection anchorage.

5,000 lb Minimum Breaking Strength

With a minimum breaking strength of 5,000 lbs, this strap provides a robust safety margin for fall arrest applications. This rating supports use in demanding structural steel environments where reliable anchorage integrity is critical.

PVC Coated Galvanized Steel Cable Construction

The galvanized steel wire rope core resists corrosion in outdoor and wet conditions, while the PVC vinyl coating protects both the cable and the structural steel surface it wraps around. This combination extends the service life of the strap compared to uncoated alternatives.

Dual Forged O-Ring Design

One large forged O-ring and one small forged O-ring allow for flexible connection configurations, including pass-through rigging on I-beam flanges. Forged O-rings provide greater strength and reliability than stamped or welded ring alternatives.

Lightweight and Portable

At just 1.10 lbs, the 4 ft cable cross arm is easy to carry and deploy, reducing fatigue for workers who need to set up multiple anchor points across a job site. Its compact form factor makes it practical for daily use in fast-paced construction environments.

Common Applications

I-Beam Anchorage

Wraps around structural steel I-beam flanges to create a compliant anchor point for personal fall arrest systems. The cable design conforms to the beam geometry for a secure, stable connection.

Steel Erection Work

Used by ironworkers and steel erectors who require temporary anchorage connectors while working on exposed structural steel at elevation.

Pass-Through Rigging Configurations

The small forged O-ring end enables pass-through rigging, allowing the strap to be looped and secured around structural members without additional hardware.

Fall Arrest System Anchorage

Serves as the anchorage connector point for self-retracting lifelines (SRLs), lanyards, and other fall arrest equipment in compliant personal fall protection systems.
