3M 7100309976 Climbing Harness 2XL 420 Lb Gray

Product Description

The 3M 7100309976 is a full-body climbing harness rated for a 420 lb load capacity, built for workers operating at height on commercial and industrial job sites. The harness features 6,000 lb rated polyester webbing and lightweight aluminum hardware, keeping the overall weight manageable across extended shifts. A nylon and polyester hybrid comfort padding system includes reflective panels for low-light visibility. The dorsal D-ring area incorporates updated geometry to help workers seat the ring correctly and maintain a safe, consistent fit throughout the work day. Quick-connect leg strap and chest strap buckles reduce donning time and minimize fit errors in the field.

This harness is suited for construction, tower work, utility maintenance, and any trade application requiring ANSI-compliant personal fall arrest equipment. The size 2XL fit range and 420 lb rated capacity accommodate larger-framed workers in residential and commercial settings. Locking torso adjustment provides a secure, repeatable fit for daily use. The gray colorway with reflective accent panels supports site visibility requirements. Licensed fall-protection installers and competent persons overseeing height work programs are the primary end users.
