Miller AC-QC/UGN Fall Protection Harness 400 Lb Universal

Product Description

The MILLER AC-QC/UGN is a full body fall protection harness rated for a 400-pound load capacity, built around the AirCore single D-ring design for lightweight comfort during extended work-at-height tasks. Constructed from durable polyester webbing, this harness features a quick-connect chest strap, quick-connect leg straps, and cam-buckle shoulder straps for fast, repeatable donning and doffing. The back D-ring serves as the primary fall arrest attachment point. An anti-tangle strap keeps webbing organized and reduces interference during movement on the job. This harness is installed and inspected by qualified personnel working in accordance with applicable fall protection regulations.

The AC-QC/UGN is suited for residential and commercial construction, roofing, utility work, industrial maintenance, and any application requiring ANSI-compliant personal fall arrest equipment. The universal sizing accommodates a wide range of body types, making it practical for crews where a single-size inventory is preferred. The AirCore design reduces harness weight and promotes airflow against the body, supporting comfort during full-shift wear.

Installation Notes

Fall protection harnesses must be inspected before each use by a competent person per OSHA 29 CFR 1926.502 and applicable ANSI Z359 standards. Power down or de-energize any electrical equipment in the work zone before donning and adjusting the harness. Follow the manufacturer's donning sequence to ensure all buckles are fully engaged and webbing is free of twists. Remove the harness from service immediately if it has been subjected to fall arrest forces or shows signs of webbing damage, buckle deformation, or UV degradation.
