Build a Post-and-Rail Fence Garden Club
Level each rail and nail it in place with galvanized 10d nails or screw it in place with 3-inch deck screws. 4. Install the Cross-Rails. Tack cross rails to the posts and mark them for cutting with a framing square. Remove the cross rails, make the cuts with a circular saw, then fasten the cross rails to the posts with galvanized 10d nails or screw them in place with two 3-inch deck screws.
