MCR Safety offers a wide variety of products to assist in the care and maintenance of your safety eyewear. The 214 eyewear cord helps you keep up with your safety glasses in style. The plastic tips on this lanyard snaps into place over the dimples found on the eyewear temples. This allows the cord to break away from the glasses should they become entangled and pulled. An easy to use take-up cinch slide allows for easy adjustability. Non dielectric - metal clamps.
