3M™ Marker Series 290 Reflecting Road Stud
The 3M™ surface mounted Series 290 Road Stud is a high performance, permanent, surface mounted reflecting road stud. The 290’s prismatic reflective lens, which is protected by an abrasion resistant coating, offers excellent reflectivity and visibility in all weather conditions and has achieved the highest ratings for night time visibility in BS EN 1463. The easily and quickly applied polycarbonate stud body is specifically designed to deliver excellent durability and dissipate impact forces.
The 3M™ Series 290 Road Stud is extremely versatile – it is suitable for use in any position, on all road surfaces and has proven itself in many countries throughout the world and is available in all approved colour combinations. Although care should be taken if the stud is being considered for use in areas of high traffic levels when combined with the 301 cast iron housing from Roadcraft and Flemings it really is the stud of choice.
The 3M™ Marker Series 290 Reflecting Road Stud is compatible with the well-established Roadcraft/Fleming 301 metal casting, creating an innovative and robust embedded non-depressible road stud. Combined, these products are designed to provide excellent long life performance in all weather conditions and on all roads, including the U.K.’s heavily used road and motorway network. The 301/290 road stud is easily installed using traditional vertical milling equipment and is supplied complete with the reflector already fitted.
The following table shows the classification achieved by the road stud in its BS EN 1463 test, along with the minimum requirements required for legal UK use - as specified in TSRGD (2016).
