The 3M™ ExoFit™ NEX full body harness (1103073C) is designed for demanding fall protection work where comfort, mobility, and fast donning matter. Built for industrial climbing and elevated tasks, it provides secure connection points for fall arrest and positioning while supporting long shifts with padded contact zones. This configuration is designed to help crews move confidently between ladders, structures, and platforms while maintaining consistent fit and hardware performance across daily use

Key Features

Multi-point connections: Includes attachment elements such as dorsal, sternal, frontal, and hip D-ring options (by configuration) to support fall arrest and positioning workflows.
Duo-Lok™ quick connect buckles: Quick-connect buckle option for faster donning and consistent closure under jobsite pressure.
Revolver adjusters: Adjuster option designed for easier, controlled fit tuning when changing layers or tools.
Trauma straps: Integrated trauma strap feature option to support post-fall suspension relief planning.
Padded comfort zones: Padding options (hip/legs/back & shoulders) help reduce pressure points during extended wear.
High-strength hardware performance: D-ring materials and buckle/adjuster tensile strengths are defined in the product specifications table for consistent PPE control.

Intended Use

This harness is used as part of a fall protection system when workers need stable fit, multiple connection options, and jobsite-ready comfort for repetitive climbing and movement. Selection of attachment points should match the task (fall arrest, restraint, positioning, rescue planning) and the site’s procedures.

Ironworkers and structural crews
Maintenance teams in industrial plants
Utilities and electrical maintenance at height (including arc-flash-controlled zones)
Construction crews on ladders, platforms, and mobile equipment
