When installing these convex mirrors, they are usually installed in corners, on pillars, or near ceilings about 8’ to 12’ high. The size of the mirror depends on space and function, the bigger the mirror the better the view!
These mirrors have a single adjustable telescopic arm with a rotating mount that allows you to position your mirror at exactly the right angle. To determine the best position for the mirror, center the view of the mirror between the two lanes of traffic that need to see each other, and then adjust it as needed to get the best angle. When anchoring, use anchors for concrete or #12-14 screws about 1”-2” long and washers for wood.
You can choose from a variety of traffic mirrors to find the one that fits your situation.
