MCR Checklite CL1 Safety Glasses — ANSI Z87.1+ Rectangular, 4-Point Ratchet Temples

The MCR Safety Checklite CL1 is the only classic rectangular, non-wraparound frame in MCR's line with 4-point ratchet-adjustable temples — two adjustment points per temple for a secure, dialed-in fit on a traditional safety-glasses silhouette. It's ANSI/ISEA Z87.1+ high-impact, in nine variants across seven tints including Amber. For workers who find wraparound frames claustrophobic, too warm, or a poor fit, the CL1 is the familiar shape done right.

Why the MCR Checklite CL1 is the rectangular-frame pick

Wraparound safety glasses aren't for everyone — some workers find the curved lens warm, visually confining, or a bad match for their face, and quietly stop wearing them. The CL1 answers with a traditional rectangular frame that feels familiar, paired with 4-point ratchet temples that dial in the fit and a full Z87.1+ rating. It's the model to reach for when a wraparound has been the reason someone pushes their glasses up. Our full Checklite CL1 review rates it 4.4/5, and the safety glasses buyer's guide covers frame-shape tradeoffs.

What the listing documents

From the published specs: ANSI/ISEA Z87.1+ high-impact rating; a classic rectangular (non-wraparound) polycarbonate frame with 4-point ratchet-adjustable temples; nine variants across seven tints — Clear, Gray, Light Blue, Amber, Silver Mirror, Blue Mirror, I/O Mirror — in Standard, Duramass, and UV Anti-Fog coatings; not OTG; base model CL010. As mcr safety checklite eyewear, the CL1 is the traditional-form member — a genuine set of rectangular safety glasses, and with its two-point temples a true ratchet temple safety glasses option.

Choosing your CL1 variant

Match the tint to the task: Clear from the clear-lens collection for indoor work, Gray for outdoor glare, Amber for low-light contrast, and I/O Mirror for shifting light from the I/O collection. The clear-vs-smoke lens guide settles the outdoor call, and the Gray UV Anti-Fog variant pairs with the anti-fog guide and anti-fog collection for humid work.

Where the CL1 sits in the MCR line

The Checklite splits by frame width: this CL1 is the full-width rectangular frame with the widest tints, and the Checklite CL1N is the narrow-bridge version for smaller faces. If you want ratchet temples on a wraparound instead, the Klondike KD7R delivers that, and the slim sport BearKat BK2 is the wraparound alternative.

Where it fits by job and crew orders

The rectangular form suits inspection, lab, assembly, and maintenance work where a wraparound feels like overkill — the manufacturing and mechanics guides rank frames by task, and smaller-faced wearers should check the small-face guide and women's fit guide. Where the hazard exceeds impact — splash, dust, vapor — step to a sealed goggle from the safety goggles collection or the broader eye protection collection.
