MCR Safety Checklite CL1 Series Safety Glasses

The MCR Safety Checklite CL1 stands apart from every other model in this collection: it is the only classic rectangular frame (non-wraparound) with 4-point ratchet-adjustable temples — two adjustment points per temple for a secure, customizable fit on a traditional safety glasses form factor. Workers who find wraparound frames claustrophobic, too warm, or incompatible with certain face shapes often prefer the CL1's more open rectangular design. Nine variants cover Clear, Gray, Light Blue, Amber, Silver Mirror, Blue Mirror, and I/O Mirror tints across Standard, Duramass, and UV Anti-Fog coatings — including the only Amber option outside the BearKat line at this price. For a narrow-bridge version of the Checklite, see the Checklite CL1N; for a wraparound with ratchet temples, see the Klondike KD7R.

Key Features

• 4-point ratchet temples — two adjustments per arm: The CL1's temples feature two ratchet-click positions each, providing front-to-back positioning and vertical angle adjustment — allowing more precise customization than single-point ratchet or fixed-temple designs.
• Classic rectangular frame (non-wraparound): An open, traditional safety glasses silhouette preferred by workers who find wrap frames too close to the face, too warm in hot environments, or who prefer the aesthetic of traditional safety eyewear over sport-wrap styles.
• Amber tint (CL114/Duramass): One of only two MCR models in this collection offering Amber — enhances contrast in overcast, foggy, and low-light outdoor conditions; preferred for driving, hunting, and variable-light outdoor tasks.
• 9 variants in one frame platform: Clear (Standard, Duramass, UV Anti-Fog), Gray (Duramass, UV Anti-Fog), Light Blue, Amber, Silver Mirror, Blue Mirror, and I/O Mirror — covering both practical indoor/outdoor needs and fashion-forward mirror options.
• Silver Mirror (CL117) and Blue Mirror (CL118): Reflective mirror tints for intense-sun outdoor use — Silver Mirror for general outdoor glare; Blue Mirror for environments with strong surface glare (water, pavement, chrome).
• $9.99 across all 9 variants: Economy price with broad tint selection makes the CL1 suitable for multi-tint safety programs covering both indoor and outdoor workers.

Applications

• Workers who prefer traditional rectangular safety glasses: Inspectors, supervisors, lab technicians, and office-adjacent workers in manufacturing who want professional, traditional-looking eyewear rather than sport-wrap frames.
• Hot environments: The open rectangular frame allows more airflow around the eyes compared to closed wraparound styles — workers in foundries, near heat sources, or in hot outdoor environments may find the CL1 more comfortable.
• Outdoor variable-light work (Amber lens): The CL1 Amber variant is one of only two Amber options in the entire MCR collection — appropriate for outdoor workers in overcast or foggy conditions who need contrast enhancement.
• Mirror tints for intense sun: Silver and Blue Mirror CL1 variants for sustained outdoor construction, landscaping, and utility work in direct sunlight.
• General manufacturing with ratchet fit: 4-point ratchet temples provide a precise, custom fit that stays in place during full-shift manufacturing work — relevant for workers whose glasses regularly shift or slide during production tasks.

ANSI Z87.1 Compliance

The MCR Checklite CL1 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.
