3M 7100175558 Hard Hat 6-point Ratchet Suspension

Product Description

The 3M 7100175558 is a standard hard hat with a 6-point ratchet suspension system, constructed from Acrylonitrile Butadiene Styrene (ABS) plastic. It meets ANSI Type I classification, meaning it provides top-impact protection for the crown of the head. The unvented, slotted shell accepts compatible accessories and attachments. The ratchet adjustment fits a universal head size, allowing quick sizing without removing gloves. This hard hat is suited for general construction, industrial, and utility work sites where overhead impact hazards are present.

This hard hat is appropriate for residential and commercial construction, industrial facilities, utility work, and general contracting environments. The slotted design allows for compatible face shields, earmuffs, and other brim-mounted accessories typically used by electricians, pipefitters, ironworkers, and general trade workers. The non-vented shell provides consistent protection in environments where airborne particles or liquid splash are a concern.

Installation Notes

Inspect the shell and suspension for cracks, dents, or UV degradation before each use. Replace the hard hat and suspension if either has sustained an impact or shows signs of damage. Follow OSHA 29 CFR 1926.100 and ANSI Z89.1 requirements for hard hat use, inspection intervals, and retirement criteria. Do not drill additional holes, paint, or apply adhesive labels over impact zones on the shell, as these actions may compromise structural integrity.
