20620 - Jackson Safety Blockhead FG Vented Fiberglass Hard Hat Full Brim

Premium Fiberglass Head Protection

The Jackson Safety Blockhead® FG Series Hard Hat (SKU: 20620) represents a fusion of modern style, robust material science, and superior comfort. Designed for professionals who demand more than just basic compliance, this hard hat features a unique contoured dome with a distinctive ridgeline. The shell is wrapped in a special water transfer decal that provides a sleek, high-tech "composite" carbon fiber appearance, ensuring you stand out on the job site while remaining fully protected.

Advanced Material and Venting

Unlike standard High-Density Polyethylene (HDPE) hard hats, the Blockhead FG is molded from special fiberglass materials. Fiberglass offers exceptional strength-to-weight ratios and superior performance in high-heat applications where standard plastics might soften or deform. This specific model (20620) is the Vented version, featuring strategically placed ventilation holes in the dome. These vents allow hot air to escape, significantly reducing heat buildup inside the helmet and keeping the wearer cooler during long shifts in hot climates or direct sunlight.

Superior Fit with 370 Speed Dial™

Comfort is paramount for safety gear that must be worn all day. The Blockhead FG comes equipped with Jackson Safety’s industry-leading 370 Speed Dial™ ratcheting headgear. This oversized adjustment knob allows for quick, easy, and precise tightening or loosening of the suspension system, even while wearing gloves. The 4-point suspension system cradles the head securely, distributing weight evenly to prevent pressure points. It accommodates a wide range of head sizes, from 6-1/2 to 8, ensuring a personalized fit for almost any worker.

Safety Standards and Application

This hard hat meets ANSI Z89.1, Class C standards. Class C (Conductive) hard hats are designed to offer impact protection but are not intended for use around electrical hazards. The full brim design provides extra utility by shedding rain and blocking sun from the neck and ears, making it an excellent choice for outdoor construction, general labor, and industrial environments where electrical shock is not a primary hazard.
