<p>The bracket is used to clamp together three poles (12, 13, 14) each perpendicular to the other two. The bracket is made up of two identical pieces (7, 8) which are joined together by a through bolt (15) which passes between the three poles. Each bracket is made up of a three fingered plate curved to the outside diameter of the poles. Each of the fingers is the same length and curved to the same curvature. The brackets may be made from cast aluminium.</p> |
