Dome Safety Mirrors are widely used for surveillance and accident prevention in retail, industrial and office environments. Made of a lightweight Perspex that will not fade or discolour, this makes the mirror great for long term placement. These safety mirrors are the ideal solution where general surveillance of a broad area is required. The Half Dome Mirror is ideal for T intersections, as it provides a 180 degree view of surroundings. Dome mirror comes complete with pre-drilled holes and instructions ready for installation. Screws and adhesive not included.
