Abstract (en)
[origin: EP1286008A2] The support has locating holes (22) on the inner pole, with letters, symbols or numbers (24) imprinted or stamped either adjacent at 90 degrees to or between the holes. Both the inner and outer poles (20,14) have an annular cross-section. The symbols run along the length of the inner pole periodically. The symbols are located every 10 to 20 mm, and preferably about 15 mm in the axial direction. An adjustment sleeve (36) is located on the support for fine adjustment of the length. A milled or knurled area (30) extends longitudinally, surrounding the symbols. The locating holes are punched out from a galvanised metal strip and then the symbols, letters or numbers are imprinted. The strip is then formed into a desired shape i.e. a pole and then welded together.
