Our reflecting road studs with dome heights of 14 mm and 19 mm are compliant with standard EN-1463-1 / EN-1463-2.

Remark: it is advisable to install these reflecting studs in areas that pose no danger for users (cyclists, pedestrians, etc.).

1 –  After deciding where the studs are to be installed, drill a hole with a minimum diameter of 106 mm and 45 mm deep.

2 –  Clean and dry the hole.

3 – Fill the hole 2/3 full with 2-component epoxy adhesive or elastomeric bitumen. Do not use cement or any alkaline material that may affect the reflecting film on the base of the stud.

4 –  Insert the stud into the hole. Use a mallet to level it flush with the ground. Immediately remove any residual adhesive from the stud.  Leave a weight on the stud until the adhesive has set (see the manufacturer’s instructions for the necessary time).

Remark: throughout these operations, make sure to protect the reflecting stud and keep it clean.

Failure to comply with these instructions may lead to the guarantee being suspended.
