I see that each time somebody is asking about existing concrete installation all you say is no this product does not work for that purpose but you neglect to mention the product that can be used for existing concrete mount.

Hello! Yes, you are correct that some of our products can be surface mounted using the proper surface mount kit... For the 5-in silver post insert for vinyl fence this is installed inside the post for in ground post applications to support either in line or gate posts if needed.
