These basalt gray door handles from the "STERK" brand are mounted on ultra-thin rosettes of only 3mm. The basalt color is very similar to the familiar anthracite gray and takes its name from the volcanic igneous rock.
The anthracite gray door handles, made of stainless steel, feature a basalt gray PVD coating and have passed multiple tests, including the PN-EN 1906:2012 fire-resistance test, the level 7 durability test (which requires no fewer than 200,000 test cycles), and a 96-hour salt spray test that resulted in a level 3 corrosion rating. They also passed the fire-resistance test, meaning they can be used on doors with an EI30 fire resistance rating.
These door handles, mounted on rosettes with a diameter of 54.5 mm and only 3 mm thick, feature a clever system with a magnetic side, ensuring the door handles are spring-loaded yet can be securely fastened with the included patent screws. The thicker, 21 mm diameter handles create a sleek and modern look.
In short, high-quality door handles on sprung metal rosettes with cams, perfect for frequent use in residential, office, or public spaces at a competitive price.
The door handles, suitable for interior doors up to 43 mm, are supplied as a pair and feature the STERK logo.
For wider doors it is always possible to send longer mounting materials on request.
