Product Description

The 3M 7012776902 is a full body fall protection harness from the X300 series, designed for workers operating at height in construction, industrial, and maintenance environments. Rated for a 420 lb load capacity, this vest-style harness is built with polyester strapping for durability and comfort during extended wear. It features quick-connect leg strap buckles for fast, secure donning, and D-ring shoulder strap buckles for upper body adjustment. The harness is sized for medium-build users and finished in gray. Licensed fall protection professionals and safety-trained tradespeople are the primary installers and users of this equipment.

This harness is suited for residential and commercial jobsites where workers are exposed to fall hazards, including roofing, structural steel, scaffolding, and elevated platform work. The vest-style design distributes load across the torso and is compatible with standard fall arrest lanyards and self-retracting lifelines connected to a dorsal or sternal D-ring. It is commonly deployed in OSHA-regulated environments requiring personal fall arrest systems.
