The Bau-style door handle continues the trends of the 1930s, which were influenced by Bauhaus and Art Nouveau. This door handle on a square rosette is made of zamak and has a matt black coating. The rosette has support cams, which means it stays in place better. In addition, the rosette is equipped with a spring so that the pusher springs back into its original horizontal position after use. This door handle construction style is delivered in pairs including BB rosettes and mounting material.
