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 an anthracite gray 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 construction style door handle comes in pairs and with a toilet/bathroom latch with support cams
