Cross Arm Strap

Cross Arm Strap — ANSI Z359.1-2007 & OSHA-Compliant Anchor Strap for Fall Protection

The Palmer Safety Cross Arm Strap (Part No. A36806) is a heavy-duty anchorage connector designed for use in fall protection systems by construction professionals and trades workers operating at height. The strap features a dual-webbing construction — 1-3/4" (1.73 in.) polyester webbing stitched onto a 3" (2.76 in.) backing webbing — providing a reinforced anchor point around structural members such as beams, columns, and poles. Available in multiple lengths from 4 ft. to 16 ft., it accommodates a wide range of structural configurations and is equipped with both a large D-ring pass-through and a small D-ring for versatile connection options. It meets or exceeds ANSI Z359.1-2007 and OSHA requirements for personal fall arrest anchorage connectors.

Technical Specifications

Available Lengths & Part Numbers

Weight by Length

Unlike single-webbing anchor straps, the Cross Arm Strap's dual-layer construction — with a narrower inner webbing stitched to a wider backing — distributes load across a broader contact surface, reducing stress concentration at the anchor point. The alloy steel hardware with golden yellow galvanized finish provides corrosion resistance suited to outdoor and jobsite environments, and the dual D-ring configuration allows connection flexibility that single-ring straps cannot offer.

Key Features & Benefits

Dual-Webbing Reinforced Construction

The 1.73 in. polyester webbing is stitched onto a 2.76 in. backing webbing, creating a layered structure that provides extra protection at the anchor wrap point. This design helps protect the primary load-bearing webbing from abrasion and edge wear when looped around structural members.

5,000 lb. Breaking Strength — Webbing and Hardware

Both the polyester webbing and the alloy steel metal components are rated to a 5,000 lb. breaking strength, ensuring the entire assembly maintains consistent load capacity throughout the system. This matched rating eliminates weak-link concerns between the webbing and hardware components.

ANSI Z359.1-2007 and OSHA Compliance

The strap meets or exceeds ANSI Z359.1-2007 and OSHA requirements for anchorage connectors, satisfying the compliance documentation requirements contractors face on regulated jobsites. Static strength testing at 18 kN for 3 minutes and dynamic testing with a 220.46 lb. test mass from 4.92 ft. free fall confirm performance to standard.

Large D-Ring Pass-Through and Small D-Ring

The inclusion of both a large pass-through D-ring and a small D-ring gives workers connection flexibility to accommodate different snap hooks, carabiners, and self-retracting lifeline connectors. This dual-ring design supports a wider range of fall arrest system configurations without requiring additional hardware.

High-Tenacity Polyester Stitching Thread

The stitching that joins the two webbing layers uses high-tenacity polyester thread, which maintains strength under load and resists degradation from UV exposure and moisture common on outdoor construction sites.

Multiple Length Options (4 ft. to 16 ft.)

With seven available lengths from 4 ft. to 16 ft., the strap can be sized to wrap around structural members of varying dimensions — from narrow beams to large columns — without excess slack that could compromise anchor geometry.

Common Applications

Steel Beam Anchorage

Loop the strap around a structural steel beam or column to create a compliant anchor point for connecting a personal fall arrest system lanyard or self-retracting lifeline.

Wood or Concrete Column Wrapping

The variable lengths allow the strap to wrap around larger-diameter wood or concrete structural members where fixed anchor hardware cannot be installed.

Utility Pole and Tower Work

Longer length options (up to 16 ft.) accommodate large-diameter poles and tower structures, providing a secure anchor wrap where conventional anchor hardware is impractical.

Temporary Anchor Point Establishment

When permanent anchor hardware is not present, the cross arm strap provides a portable, reusable anchor solution that can be repositioned as work progresses across a structure.
