Klein Tools Safety Glasses — Gasket & Over-The-Glasses Styles

ANSI Z87.1+ indicates the glasses meet the high-impact test criteria of the ANSI/ISEA Z87.1-2020 standard — a more demanding test than the basic Z87.1 rating. The "+" suffix specifically means the lens and frame have passed the high-velocity ball drop and penetration tests. OSHA 29 CFR 1910.133 references ANSI Z87.1 as the applicable standard for occupational eye protection.

Yes — both the foam perimeter gasket and the nylon retention strap on the 60538/60471 gasket models are designed to be replaced. Klein Tools sells replacement gaskets and straps separately. Replacing a degraded gasket restores the dust seal without replacing the entire frame and lens.

The 03006 and 03007 OTG models are designed to fit over most standard prescription frames. Oversized or wrap-around prescription frames may not fit — check the inner dimensions (approximately 150mm wide × 42mm tall at the lens opening) against your Rx frame before purchasing. If your Rx frame is too large for standard OTG glasses, prescription safety inserts or a dedicated prescription safety lens is the alternative.

Choose gasket glasses when your hazard assessment (per OSHA 1910.132/1926.102) identifies fine airborne particles, concrete dust, grinding debris, chemical mist, or any hazard that can enter through the gap between a standard safety glass frame and the face. OSHA does not specify gasket glasses by name but requires protection adequate to the hazard — a task-specific PPE assessment determines whether open-frame safety glasses are sufficient or whether a sealed perimeter is required.

Clear lenses (60538 / 03006) transmit approximately 90%+ of visible light — best for indoor, low-light, or variable lighting environments where color recognition must be preserved. Gray lenses (60471 / 03007) reduce visible light transmission by approximately 15–25%, making them comfortable for bright outdoor conditions. Gray is a neutral tint that does not distort color perception. Neither lens is rated as a shade for arc welding — use dedicated welding shades for arc and gas welding operations.

Yes. All four variants provide UV protection. The OTG models (03006/03007) are specifically rated ANSI U6, which blocks 99.9% of UVA, UVB, and UVC radiation. The gasket models provide UV protection but may not carry the explicit U6 marking — check the product marking or data sheet for your specific compliance documentation needs.

The gasket models (60538/60471) provide a sealed perimeter that offers indirect-vent goggles-style protection against splash from the front. However, they are not tested to ANSI Z87.1 splash-specific criteria (D3 marking) unless marked accordingly — check the lens or frame marking for the "D3" designation if your SDS requires splash-rated eye protection. True chemical splash goggles with indirect vents are the appropriate choice for direct chemical handling per OSHA 29 CFR 1910.133.

Use a clean, dry microfiber cloth or the lens cloth included with the glasses. Avoid paper towels, abrasive cloths, and acetone/alcohol-based cleaners — these degrade anti-fog coatings rapidly. Rinse with clean water before wiping if debris is present. Scratches in the coating reduce both anti-fog and anti-scratch performance; replace lenses or the full unit when the coating is compromised.

Yes — all four variants carry both ANSI Z87.1+ and CSA Z94.3 certification. CSA Z94.3 is the Canadian equivalent standard for industrial eye protection, required under provincial OH&S regulations. Workers on Canadian job sites requiring certified eye protection can use these glasses without a separate CSA-specific purchase.
