Description Designed for 360 degrees of omni retroreflection, the glass road stud 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. It provides a powerful means of delineation with a fall in reflectivity and raises conspicuity of hazardous road layouts, junctions and curves within the beams of vehicle headlights. Moreover its operational life comparable with road surfacing materials Housing Material: Tempered Optical Glass Viewing Angle: 360 degree Optical Principle: Catadioptric Color: white yellow green blue Mechanical Resistance: 25 tonnes Optical Performance: 100mcd Impact Resistance: 25 joules Reflector Size (Height): 19.5mm Product Size: Diameter 100mm Height 50mm Diameter 50mm Height 50mm Features: 1.wont easily be damaged by cleaning or by removing the snow on the road 2.easy to maintain if damaged, easy to install, low maintenance 3.visible and reflective even in bad weather like heavy rain or snow,adding aesthetic value, safety on the road 4.distinguishes traffic lane with self-reflection feature.Its strong reflector protects the cars from twisting and sinking into the road and helps prevent traffic accidents especially at night 5.dirt resistant design and wont easily get dusty regardless of the road condition 6.heavy duty toughened glass body withstands 25 Tonnes 7.high performance and lasts for five years Application: 1.replaces traditional and surface mounted reflectors 2.especially suited to roundabouts,wet/dark accident cluster sites 3.definitions of blind summits Installation: 1.Adhesive bituminous grout secures the 360 within a milled cavity 2.Epoxy adhesive can be applied with caulking gun to secure reflective markers to pavement.
