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

Product Description

The MILLER ACA-QC/UGN is a full body fall protection harness rated for a 400-pound load capacity. Built in the AirCore Single D-ring style, it is constructed from polyester webbing and designed for use in elevated work environments where fall arrest systems are required. The harness features a back D-ring attachment point, quick-connect leg straps, a cam-style shoulder strap buckle system, and a quick-connect chest strap. An anti-tangle strap and stretchable design elements support freedom of movement during installation and maintenance tasks. This harness is installed by workers required to comply with fall protection regulations on job sites.

The ACA-QC/UGN is suited for general industry and construction applications where a full body harness is mandated by OSHA or site safety programs. The universal sizing accommodates a wide range of body types, reducing the need to stock multiple size variants. Typical applications include work on rooftops, scaffolding, elevated platforms, utility structures, and aerial lifts. It is appropriate for use by electricians, HVAC technicians, plumbers, and other trades working at height on commercial and residential job sites.

Installation Notes

Fall protection harnesses must be inspected before each use for webbing damage, buckle integrity, and D-ring condition. Donning and adjustment should follow the manufacturer instructions to ensure proper fit across chest, shoulder, and leg straps. Installation and use of fall protection systems is subject to OSHA 29 CFR 1926 Subpart M for construction and 29 CFR 1910 Subpart D for general industry. Never attach a harness to an anchor system that has not been evaluated for the required fall arrest load.
