This involves cutting, measuring, and fitting pieces of lumber together to fit securely into place. Attaching pergola rafters may seem like a daunting task, but it’s actually quite simple.
The first step is to mark the location of the rafters on the posts. Once the locations are marked, drill pilot holes for the lag screws. Next, align the rafters with the marks on the posts and insert the lag screws. Be sure to use washers on both sides of the rafter to prevent any movement. Finally, tighten all of the screws until the rafters are secure. In this blog post, You will learn how to attach pergola rafters in detail.
