STAIRTEC SWR non-slip elements with their modern, sophisticated design are an innovative solution to characterize stairways and satisfy safety requisites in an alternative way, rather than using linear profiles. STAIRTEC SWR consists of a narrow button in stainless steel with rounded visible part suitably grooved, that serves to customize stairways in wood or marble with innovative, sophisticated design. Installation and assembly can be made in the workshop or directly at the site, by providing a simple hole with a recommended interaxis of 70 mm. Applied to wood, the hole need only have a diameter of 6,5 mm, then the SWR element can be hammered in. On stairways in marble, stone or ceramic, it is preferable to drill a hole measuring 7 mm and fasten the profile with suitable supporting glue. The grooves will also facilitate the mechanical grip with the part in stainless steel.
