This mount is just what you need to install 4-inch hollow vinyl posts on concrete or a deck.
It creates a stable base over which you slip a 4 in. x 4 in. vinyl fence post. Hide screws with the included post skirt. Then, finish your project and enjoy the rest of your day.
NOTES: When installing in concrete, you’ll need to drill a hole at least 3.5 inches deep. On decks, you’ll drill into the substructure. The substructure can be a 2x6 cross brace secured between the joists. Install on level surfaces only.
