Provides a powerful means of delineation with a fall in reflectivity. The 360 degree even reflects the weaker light at the perimeter of the headlight beam, enabling the driver to see the 360s before the beams fall directly on the stud. Raised conspicuity of hazardous road layouts, junctions and curves within the beams of vehicle headlights. Superlative Reflectivity values even on blind summits and bends Operational life comparable with road surfacing materials Dirt Resistant Design Small profile suited to two wheeled road users. Heavy duty toughened glass body withstands 35 Tonnes Applications Replaces Traditional and surface mounted reflectors Especially suited to roundabouts Wet/dark accident cluster sites Definitions of blind summits Housing Material: Tempered Optical Glass Viewing Angle: 360 degree Optical Principle: Catadioptric Mechanical Resistance: 35 tonnes Optical Performance: 100mcd Impact Resistance: 25 joules Reflector Size (Height): 19.5mm Product Size: BLDD100 Diameter 100mm Height 50mm BLDD50 Diameter 50mm Height 50mm Installation: Adhesive bituminous grout secures the 360 within a milled cavity Optional Colours: White, Red, Amber, Green
