Studson SHK-1 Standard Brim Non-Vented Safety Helmet Type 2 Class E L/XL 58-63cm

STUDSON SHK-1 Non-Vented Safety Helmet  The SHK-1 Non-Vented is built for environments where a sealed shell isn't optional. Class E rated to 20,000 volts, it carries the same Koroyd impact core, Twiceme NFC, and Fidlock chin strap system as the vented model — without the openings that disqualify vented helmets from electrical applications.  Built for electricians, utility workers, and anyone working in or around high-voltage environments.  Key Features  Class E Non-Vented Shell Fully sealed ABS shell rated to withstand up to 20,000 volts. No vents means no conductive pathways — the right choice for electrical and high-voltage job sites.  Rear Dial Fit System One-handed micro-adjustment with an extendable front brow pad for additional fine-tuning. Dial in your fit at the start of the shift.  Accessory  Ready Compatible with the SHK-1 Half Shield, Telescoping Headlamp, Ear Defenders, Neck Shade, and more. Same accessory platform as the vented model.
