LE18134L D-Ring Extender

LE18134L D-Ring Extender — 18 in. Single Leg Webbing Extender for Fall Protection Systems

The LE18134L is an 18-inch single-leg D-ring extender designed for use in personal fall arrest systems (PFAS). It features 1-3/4 in. wide polyester webbing with a loop on one end and a large D-ring on the opposite end, allowing workers to reposition or extend the dorsal D-ring attachment point on a harness. Built for trades professionals and contractors working at height, this extender meets or exceeds ANSI Z359.1-2007 and ANSI Z359.11-2021 compliance standards. It is manufactured and tested by Palmer Safety and is suited for integration into compliant fall protection assemblies.

Technical Specifications

Unlike basic webbing loops or fixed-position harness attachments, the LE18134L provides a dedicated large D-ring connection point that can extend or reposition the harness attachment for improved connector compatibility. The combination of high-tenacity polyester stitching and a 5000 lb. static strength rating ensures the extender meets the same structural demands as the primary fall arrest components it connects to. Dual compliance with both ANSI Z359.1-2007 and ANSI Z359.11-2021 reflects updated testing and conformance documentation over the product's service life.

Key Features & Benefits

Large D-Ring Attachment Point

The large D-ring on one end provides a wide, accessible connection point for snap hooks, carabiners, and other fall arrest connectors. This reduces fumbling during connection and accommodates a broader range of compatible hardware.

1-3/4 in. Wide Polyester Webbing

The 1.75 in. wide polyester webbing (tolerance ± 0.04 in.) provides a robust, load-bearing strap that distributes forces effectively. Polyester webbing resists UV degradation and maintains strength across typical jobsite environmental conditions.

High-Tenacity Polyester Stitching

Stitching thread is high-tenacity polyester, matched to the webbing material for consistent performance under load. This construction minimizes the risk of thread failure at the critical sewn termination points.

5000 lb. Static Strength

Tested to 5000 lbs. for 1 minute, the LE18134L meets the structural strength requirements for use in personal fall arrest systems. This rating aligns with the connector and harness hardware it is designed to work alongside.

ANSI Z359.1-2007 and ANSI Z359.11-2021 Compliance

Compliance with both ANSI Z359.1-2007 and the updated ANSI Z359.11-2021 standard confirms the extender has been tested and documented by a qualified PFAS technician. Contractors can incorporate this component into compliant fall protection systems with confidence.

Single-Leg Configuration

The single-leg design keeps the extender simple and lightweight, adding minimal bulk to the harness assembly. The loop-on-one-end, D-ring-on-the-other configuration allows straightforward integration at the dorsal attachment point of a full-body harness.

Common Applications

Dorsal D-Ring Extension on Full-Body Harnesses

Used to extend or reposition the dorsal D-ring attachment point on a full-body harness, improving connector access and compatibility with lanyards or SRL snap hooks.

Fall Arrest System Assembly

Integrated as a connecting component within a personal fall arrest system (PFAS) where a standard harness D-ring position does not align with the required anchor or connector geometry.

Connector Compatibility Bridging

Provides a large D-ring interface when the primary harness attachment point is a loop or smaller ring, enabling connection of hardware that requires a D-ring gate opening.

Compatible Materials

• Full-body safety harnesses with dorsal or sternal attachment loops
• Snap hooks and carabiners compatible with large D-ring profiles
• Self-retracting lanyards (SRLs) with D-ring connectors
• Shock-absorbing web lanyards
• Rope grabs and attached lanyards
