Cantilever post mount bracket options for use with Comunello "M" series carriages. Securely attach each carriage to a 4-in round or 4-in square support post. The sturdy galvanized steel brackets offer a traditional installation method for the installer, allowing for an easier installation by eliminating the need to pour a large foundation. Post brackets also offer easier adjustment and gate alignment. No cement pad is required, but we recommend that each cement embedded post have a minimum hole diameter of 16" and a minimum depth of 48".
