Miller H7IC3A4 Fall Protection Harness 4XL 420 Lb

Product Description

The MILLER H7IC3A4 is a full-body personal fall protection harness from the Miller H700 Series, designed for use at elevated worksites where fall arrest is required. Built from polyester webbing with a lightweight construction, it supports a load capacity of 420 pounds and carries a tensile strength rating of 5,000 pounds. The harness features multiple D-ring attachment points — back, front, and side — giving workers and site supervisors flexibility in rigging configuration. A one-pull trauma relief step is integrated directly into the harness to help address suspension trauma risk while awaiting rescue. Licensed safety professionals, riggers, and qualified competent persons typically specify and inspect this equipment.

The H7IC3A4 is sized for 4X-Large users and fits residential construction, commercial high-rise, industrial, and utility worksites where OSHA fall protection requirements apply. The configurable leg strap design allows adjustment to fit individual body types, and modular lightweight accessory straps support attachment of compatible tools and pouches without adding significant weight to the system. This harness is well-suited for electricians, ironworkers, roofers, and other trades working at height on scaffolding, aerial lifts, or structural steel.

Compatibility

Installation Notes

Harness fitting and inspection must be performed by a competent person as defined under OSHA 29 CFR 1926.32. Before each use, inspect all webbing, hardware, and stitching for wear, cuts, chemical damage, or deformation and remove the harness from service immediately if any defects are found. Do not modify or alter webbing, D-rings, or stitching in any way. A complete fall arrest system requires a compatible anchorage point rated for fall arrest loads — the harness alone does not constitute a complete fall protection system.
