| | AAI Gymnastics Horizontal Bars,Used Gymnastics Hi Bar, Demo High Bar (Site not responding. Last check: 2007-11-02) |
 | | The bar, made of high strength steel, treated to a minimum yield of 201,000 psi, has a shot pinged finish to reduce bar fatigue. |
 | | If the bar is then flexed hard enough and often enough, the crack can spread deeper into the bar and cause it to break. |
 | | Based on data supplied by the FIG Safety Symposium, AAI strongly recommends that the horizontal bars and mounting collars be examined for wear on a regular basis, and be replaced every three (3) years, to reduce the possibility of breakage.The newer moves being performed are applying greater impact loads and vibrations on the bar. |
