MCR Safety Klondike KD7R Series Safety Glasses

The MCR Safety Klondike KD7R starts where the Klondike KD7 ends: same wide-wrap polycarbonate frame and ANSI Z87.1+ certification, but with ratchet-adjustable temples that click into precise positions for a secure fit regardless of head size, hat layering, or ear protection. Workers who find standard temples either too loose (glasses sliding during active work) or too tight (pressure on temples during full-shift wear) benefit directly from the ratchet mechanism — one adjustment per shift, stays in place. Available in 7 variants across Clear, Gray, Light Blue, and I/O Mirror tints with Duramass, UV Anti-Fog, or MAX6 Anti-Fog coatings. For the non-ratchet KD7, see the Klondike KD7; for the widest KD tint selection including Amber and Blue Diamond Mirror, see the Klondike KD1.

Key Features

• Ratchet-adjustable temples: The KD7R's temples click through discrete positions — no continuous friction adjustment that can slip — giving workers a repeatable, secure fit that stays positioned through bending, tool use, and active work without tightening against the skull.
• Wide wraparound coverage: The Klondike frame extends significantly past the brow and temple compared to standard safety glasses, reducing side-entry of particles, debris, and incidental splash from lateral directions.
• Three coating tiers: Duramass scratch-resistant hard coat; UV Anti-Fog (basic anti-fog + UV); MAX6 Anti-Fog (MCR's top-tier anti-fog, 10× more effective than standard) — select based on your primary environmental hazard.
• Light Blue tint option (KD7R13AF): Provides a low-contrast outdoor tint for overcast or variable light conditions — less darkening than gray but more comfortable than clear in mixed outdoor/indoor environments.
• I/O Mirror tint (KD7R19AF): Indoor/Outdoor mirror shifts between lighting environments without switching glasses — appropriate for workers moving between bright outdoor areas and dimmer indoor work zones.
• Polycarbonate lens with UV400: Blocks 99.9% of UVA and UVB radiation across all tint options. $9.99 economy price makes the KD7R suitable for bulk stocking.

Applications

• Active construction and trades: Workers on scaffolding, roofing, or framing who bend frequently or change positions throughout the shift — ratchet temples prevent glasses from sliding to the nose during activity.
• Layered PPE environments: Workers combining hard hats, ear muffs, and safety glasses — ratchet temples allow precise micro-adjustment to fit around ear muff cups and hard hat brim without the temples pressing or loosening.
• Workers with variable head sizes or hair styles: Job site crews with diverse workforce demographics — a single KD7R model covers a wider range of fit needs than fixed-temple alternatives.
• General manufacturing and warehousing: Wide wrap coverage plus the ratchet secure fit makes the KD7R appropriate for full-shift wear in environments combining overhead particle risk and lateral debris.
• Outdoor maintenance and landscaping: Light Blue or I/O Mirror variants for overcast outdoor conditions; ratchet temples maintain position during physical landscaping work.

ANSI Z87.1 Compliance

The MCR Klondike KD7R carries ANSI/ISEA Z87.1+ High Impact certification — required for occupational eye protection under OSHA 29 CFR 1910.133 (general industry) and OSHA 29 CFR 1926.102 (construction). The Z87.1+ high-velocity rating confirms the polycarbonate lens withstands a 1/4-inch steel ball at 150 fps without fracture.

Polycarbonate inherently blocks 99.9% of UVA/UVB radiation. Employers must conduct a hazard assessment per OSHA 1910.132(d) and provide ANSI Z87.1-compliant eye protection when flying particles, chemical splash, dust, or radiation hazards exist.
