(h) The tops of the cover boards may be cut to many different designs such as dog ear (corners cut off at 45 degree angles), gothic (two arc shaped cuts that meet in the center to form a graceful point), standard point (boards cut to a point with 45 degree angles), or domed or rounded top (where the top is cut to a half circle). There are many shapes and styles that may be custom cut at specific request. Post tops may also be cut to several decorative shapes such as pyramid, gothic, domed and chamfered. Also, shaped terminals may be screwed onto the tops of posts.
