Posts and Rails
Posts are set directly into the box and fastened with bolts or lag screws. By using these post supports you can eliminate post-hole digging and concreting. Another popular form of post base is a 4x4 in. (102mm x 102mm) metal saddle which can be set on a concrete pad and to which the post can be nailed or lag screwed. You can also use metal saddles to connect railing posts to a wood deck. One easy way to secure fence rails to posts and to simplify corner attachments, is to use aluminum or galvanized metal brackets similar to joist hangers.
