When building a split rail fence, what must be done first for proper installation?

When building a split rail fence, the first step for proper installation involves securing the corner posts before inserting the rail ends. Corner posts serve as critical structural elements that help define the layout and alignment of the fence. By setting the corner posts first, you establish a strong framework from which to measure and position the other posts and rails. This foundational step ensures that the entire fence will be straight and stable, providing the necessary integrity for the fence line.

Setting corner posts first allows for correct spacing and alignment of the rails that will connect to these posts. It also helps in determining the exact angles and directions of the fence, particularly in areas where changes in direction occur. Consequently, this method conveys the importance of starting with the highest structural elements to ensure that subsequent steps can be completed accurately and effectively.
