1/2 Inch Brass Horizontal Sidewall Fire Sprinkler Head is used in many fire fighting applications. These sprinklers stand out from a wall and have a deflector that sprays water away from the wall in a half-circle spray pattern. A second deflector also sprays water back toward the wall so that the wall is protected. These are used when sprinklers cannot be located in the ceiling.
