The stylish Bastian 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 anthracite gray Bastian door handle comes in pairs and with a toilet/bathroom lock with support cams that allow you to easily open and close the toilet door.
