Stimsonite C80 Road Stud

Product Highlights:

Injection-Modded High-Impact polymers provide extra endurance

Cellular Lens design allows lens to continue functioning after damage.

Lens reflectivity was maximised using advanced optics; initial brightness at least doubles ASTM standards.

Patent pending sure grip bottom matched with engineered polymer maximises adhesion to the road way.

Marker Strength:

Our marker durability means fewer replacement occurrences, saving money and road closures.

 The modular lens continues to provide delineation after impact, resulting in safer driving.

Marker Lens Brightness:

Our brighter lens lasts longer and provides more safety for motorists, particularly in wet weather and for older drivers.



Stimsonite 980S

The Stimsonite 980S, a permanent road stud, comes with a shank.


Aluminium Road Stud

The body of the Aluminium road stud is made from an extruded aluminium profile. The unit experiences none of the cracking associated with die-cast aluminium. The lowest reflective glass element row in the popular 43 element reflector is nearly 12mm above the road surface, largely eliminating loss of reflectivity due to rain or embedding in soft tar.

Optional tempered steel bolts provide the road stud with solid anchorage


Width of stud above road surface: 10 cm
Length of stud above road surface: 9.6 cm
Height above road surface: 2.2 cm
Length of shank ( below road surface ): 6.3 cm
Maximum width of shank ( tapered ): 1.7 cm

The 60 degree leading edge of a conventional road stud is reduced to 51 degrees by the gently sloping run-up ledge, which facilitates better traffic cleaning action.

Grooves in the under surface improve the road stud’s anti-twist positional stability and reduces the amount of adhesive required by up to 50 %. Their dovetail shape increases the strength of the adhesive bond to the road.

To minimize impact the road stud has a low 13.2mm ridge which is only 21mm wide onto the top. Impact forces are spread over a relatively large "footprint". Because the road stud is narrow, radial tyres wrap around it and transfer most of the vehicle's weight
