What's striking about the door handles of the 'STERK' brand is the high manufacturing standards, excellent material quality and all this at an attractive price.
This round door knob, made of stainless steel, has passed several tests, including the PN-EN 1906:2012 fire resistance test, meaning it can be used on doors with a fire resistance rating of EI30, and a 96-hour salt spray test, which resulted in a corrosion level 3 rating.
In short, a very high-quality door knob on metal rosettes with cams, perfect for use in residential, office, or public spaces at a competitive price.
This doorknob is mounted on a round rosette with a diameter of 53 mm and a thickness of 9 mm. It is suitable for interior doors up to 43 mm thick, is supplied individually, and features the STERK logo.
For wider doors it is always possible to send longer mounting materials on request.
