All N12 Circular Glass Indoor Convex Security Mirror 12 Diameter Pack of 1

Size: 12 inches The All circular glass indoor convex security mirror is a circular, convex, glass mirror that reflects a wide angle image at a diminished size to extend a field of view to help a person around obstacles for safety, or monitor a wide area for efficient surveillance. Glass is scratch resistant, withstands frequent cleaning, and reflects a clear, bright image. The mirror comes with a swivel mounting bracket that makes the mirror adjustable to a wide range of angles. It has a tempered hardboard backing for good strength-to-weight ratio in indoor applications. Tempered hardboard is a high-density fiberboard that has been coated with linseed oil and then baked to increase its water resistance, rigidity, and tensile strength.

Safety mirrors are sometimes called security mirrors, and they can be used to extend the view of security personnel, or to help monitor factory workers and automated processes to improve quality control and productivity. For convex mirrors, objects will appear to be further away than they are, and will be easier to in a larger mirror. Depending on visibility conditions and the viewer's eyesight, objects will usually be recognizable within about 1 ft. of distance (including distance from eye to mirror, and from mirror to object) for each inch in mirror diameter. All Industries manufactures safety and security mirrors. The company, founded in 1958, is headquartered in Chicago, IL.
