THE POINTS OF THE TRAINGULAR SHAPE POINT UPSTREAM AND THE MEMBERS ARE ARTICULATED ABOUT A GENERALLY HORIZONTAL AXIS. A SECOND MEMBER, USED IN CONJUNCTION WITH THE FIRST IS GENERALLY RECTANGULAR IN SHAPE WITH A SINGLE PLANAR EDGE SURFACE. THIS MEMBER IS LATERALLY CURVED FROM THE LOWER EDGE OF THE PLANAR SURFACE UPWARDLY TO THE OUTER EDGE OF THE MEMBER.
