The Lisa door handle on a round rosette is made of stainless steel and then brushed, giving the handle a matt appearance. Thanks to the use of stainless steel, this product has a long service life. This doorknob comes in pairs and the rosette has support cams to better hold the doorknob in place. A PZ rosette with support cams is also supplied with this door handle. In addition, this door handle meets the requirements of the European Standard 1906, which focuses on, among other things, the sustainability, robustness and safety of door and window fittings. This door handle was tested for intensive use and received usage class three.
