The Speaker Guard helps protect speakers from vandalism and accidental damage. This protective speaker cage is constructed of tough, 9-guage steel wire that is coated with corrosion resistant white polyester. These wire cages for the protective speaker cage are highly recommended for areas where abuse is severe, or it is imperative speakers continue to operate. Currently, there are three models for this product series. The installation process is fast and easy with all brackets, screws and anchors provided. If there are any questions about the installation process, please view the install sheet in the Literature tab on the web page.
