Wide-angle Convex Detection Mirrors are perfect for eliminating blind spots and for preventing intersection accidents outdoors because the special convexing affords the widest angle of vision. Additionally, these safety mirrors are equipped with a patented swivel assembly and are adjustable to most any position or angle. Constructed with a high-impact ABS plastic backing with a weatherproof vinyl-coated aluminum lock edge, these industrial mirrors are 20% brighter than glass mirrors. These 18", 26", 30", 36" or 48" diameter Convex Detection Mirrors are easy to install; simply mount with the brackets provided in the container.
