These are a nice very stout speaker mounting bracket intended for the TOA F 500/600 speaker. I am sure it would be easy to use these with other speakers of similar size. Wall mounting hardware is not included. Potential for scuffs and minor scratches from being an open box. 

Listing has them sold by the piece. Total of 4 available. I have more brackets listed as well. Thanks for looking and let me know if you have any questions. 

Happy to combine shipping
