  • Step 1 : Lay out and dig the postholes

    Lay out and dig the postholes

    Lay out the site for the divider using stakes and string. The 5 posts should be spaced so that there is 4 feet between them and set deep enough to meet your local building code. Most codes require post holes at least as deep as the frost line, but check your local code.

  • Step 2 : Install the channels

    The lattice is secured to the posts with U and H shaped channels. These channels are attached to the post with galvanized deck screws

    . Install the channels Drill the oversized pilot holes through the plastic U and H channels and leave the screws a little loose when you install the channels so you allow for expansion. Install the channels on the posts before you place them in the holes.

  • Step 3 : Install the posts

     Install the posts  Install the posts

    Fill the bottom of the holes with crushed stone. Place the corner post in the hole and backfill loosely with dirt until the post stands upright by itself. Use the level to get it straight. Then place the two center posts into their holes. The channels on the corner post and center posts should be 48 inches apart so the lattice panel will fit between the channels. Adjust the position of the center posts and then loosely fill the holes with dirt. Temporarily place the lattice into the channels to maintain spacing.

    Next put the end posts into the holes and adjust the spacing to 48 inches. Don't move the center posts. Loosely fill the holes with dirt and test fit the lattice. Adjust the post as needed.

  • Step 4 : Install the lattice panels

    Install the lattice panels

    Fasten the lattice panels to the posts with galvanized screws and screwdriver. Drill slightly oversized pilot holes through the channels and lattice every 24 inches.

    Install the lattice panels Don't overtighten these screws to allow for expansion. Use a carpenter's level to make sure the divider is straight and level. Then use the end of a scrap of lumber to tamp the dirt around the post.
