SHK-1 Full Brim HighBar Non-Vented

SHK-1 Full Brim HighBar Non-Vented Safety Helmet

The SHK-1 Full Brim HighBar Non-Vented is a Class E, ANSI/ISEA Z89.1-2014 Type I & II certified safety helmet built for job sites requiring electrical protection up to 20,000 volts. The defining feature is the HighBar chin strap system — a dial-adjustable, mono-style design that sits above the jaw for a consistent, hygienic fit that doesn't shift or absorb sweat over long shifts. Koroyd impact absorption and Twiceme NFC are integrated throughout. Fully sealed non-vented shell. Full brim coverage on all sides. One size fits most, 53–63 cm. Available in 4 colors. Weight: 567 g (1.25 lbs / 20 oz).

What makes the HighBar chin strap different?

The HighBar is a dial-adjustable mono-style chin strap system that replaces traditional buckles and fabric straps. A grip ring dial tightens and loosens the arms with a clockwise or counter-clockwise twist — precise micro-adjustment even with gloves on. The arms are made from an anti-microbial nylon blend that resists sweat and bacteria, and flip up out of the way when not in use. A padded chin cup keeps the system secure and in place through long shifts. For crews in high-wear, dirty, or wet environments, the HighBar is built to stay cleaner, last longer, and fit more consistently than any fabric strap system.

What safety standards does the SHK-1 Full Brim HighBar Non-Vented meet?

The SHK-1 Full Brim HighBar Non-Vented is certified to ANSI/ISEA Z89.1-2014 (R2019) Type I & Type II, Class E. Class E certification means the helmet is electrically rated to 20,000 volts AC — the highest electrical rating available under ANSI standards. Type II certification covers impacts from the top, front, side, and rear. This helmet is not certified to CSA Z94.1 Type II (Canada), EN 397, or EN 12492.

Note: Always verify helmet class matches your site's assessed electrical hazards before use.

Why non-vented for electrical work?

A non-vented shell has no openings in the outer surface — eliminating any pathway for electrical conductivity through the helmet. Vented helmets, regardless of their electrical class rating, cannot achieve Class E certification because the vents create a potential conductive path. If your job site involves electrical hazards up to 20,000 volts, a fully sealed non-vented shell is required. The SHK-1 Full Brim HighBar Non-Vented is built specifically for those environments.

How does the SHK-1 Full Brim HighBar protect against impact?

Koroyd's welded tubes crumple instantly on impact, absorbing maximum force and minimizing energy transferred to your head. Engineered to protect against both direct and angled impacts — may reduce the risk of suffering a life-changing injury. The full brim shell provides additional coverage over the standard brim, directing rain and debris away from the face and neck on all sides. ANSI-certified for industrial use.

What is Twiceme NFC and how does it work?

An NFC chip embedded in the helmet shell stores emergency contact and medical information. First responders can access it instantly with any NFC-enabled device — no app required, no power source needed. Setup takes under two minutes through the Twiceme app. Information is stored on the chip itself, not in a cloud database, meaning it's accessible even without cellular signal on remote job sites.

What size SHK-1 Full Brim HighBar Non-Vented do I need?

The SHK-1 Full Brim HighBar Non-Vented is one size fits most, with an adjustable range of 53–63 cm (6 5/8 to 7 7/8 hat size). The 360° micro-dial fit system lets you fine-tune the fit across that full range.
