MSA 475363 Hard Hat Front Brim Slotted 4 pt Ratchet Red

MSA V-Gard Hard Hat Front Brim Red

The MSA 475363 is a Type 1 Class E hard hat built from polyethylene with a front brim and red finish. It uses a four-point ratchet suspension that adjusts to fit head sizes from 6-1/2 to 8. Side accessory slots allow attachment of compatible hearing or face protection. The hat meets ANSI Z 89.1 2014 and CSA Z 94.1 2015 standards for industrial head protection.

Upgrading From Basic Caps To Ratchet Suspension

Workers replacing a pin-lock or non-slotted cap gain tool-free fit adjustment and accessory mounting points. The jump is worth it when daily tasks require frequent fit changes or when adding earmuffs or visors without drilling the shell. Buyers who need a full brim for sun and rain runoff should choose a different style.

Limits Of Type 1 Class E Protection

Type 1 ratings cover impact to the top of the shell only; they do not address side or rear impacts. Class E provides dielectric protection up to 20 000 volts but the shell is not vented, so heat buildup can occur in hot environments. Polyethylene degrades under prolonged UV exposure, so the hat must be inspected and replaced per the manufacturer’s service-life guidelines.
