Front-Brim Hard Hat for Head Protection
The MSA 477477 is a Type 1, Class E hard hat built with a front brim and a polyethylene shell. It meets ANSI/ISEA Z 89.1-2014 and CSA Z 94.1-2005 standards for impact and electrical protection. The four-point ratchet suspension adjusts to fit head sizes 6 through 7-1/8.
Suited for General Worksite Use
Workers needing ANSI Type 1 top-impact protection and Class E electrical insulation up to 20 000 volts will find this hat appropriate. The slotted sides accept common accessory attachments such as face shields or hearing protection. Buyers who require a full brim for sun and rain runoff, or a vented shell for airflow, should look at a different model.
Four-Point Ratchet Suspension System
The defining specification is the four-point ratchet suspension that lets the wearer tighten or loosen the fit with a simple turn of the knob. This mechanism distributes force across four contact points and allows quick, one-handed adjustment without removing the hat. If a pin-lock or fewer suspension points are preferred, this is not the correct part.

Questions about this item
Will the side slots on the MSA 477477 accept the same accessory clips I use on my current hard hat?
The side slots follow the standard accessory mounting pattern used on V-Gard helmets, so most existing face-shield, hearing-protection and lamp brackets will fit without modification.
How can I confirm the ratchet suspension is holding the shell at the correct clearance after I put it on?
Tighten the ratchet until the helmet feels secure, then check that a finger can slide between the shell and the suspension crown; the 4-point system maintains the required impact gap when properly adjusted.
Does the 477477 come with a chin strap or sweatband, or do I need to order them separately?
The box contains only the polyethylene shell and the 4-point ratchet suspension; chin straps, sweatbands and any slot-mounted accessories are sold separately.
