<p>A pole assembly (100) is provided, the pole assembly (100) comprising a first tubular pole (102) and a second tubular pole (112), the first pole (102) comprising a central longitudinally extending portion (104) having a first wall thickness and a longitudinally extending coupling portion (106) adjacent the central portion (104), the coupling portion (106) having a second wall thickness, the second wall thickness being greater than the first wall thickness, the first and second poles capable of being coupled in an end to end configuration with an end portion of one of the first and second poles extending within the other of the first and second poles, the coupling portion of the first pole overlapping the second pole, whereby a coupling between the poles may be formed by applying a radially compressive force around the coupling portion of the first pole.</p> |
