Premium solutions for surface-mounted installations
Elegant, refined, emotive: Black has been in vogue in architecture and interior design for many years. The light-absorbing non-colour shines in every environment, enhancing the ambiance of many different interiors, in both residential and commercial buildings. At the same time, surface-mounted installations are experiencing a revival as part of the trend for the industrial style. With its BlackLine, OBO presents a unique product range that meets both trends: system solutions for surface-mounted installations, now available in stylish black. The portfolio features cable support, cable routing and connection and fastening systems, among others. Whether retro or industrial style – our products from the OBO BlackLine range enable cohesive design statements that integrate seamlessly into modern architecture, increasing the value of the properties.
