A method for consistently placing a crossbar on a pin on a standard used in a vertical distance field event such as high jump and pole vault. The crossbar has a crossbar end with a directional index on at least one surface. In another example embodiment, the crossbar end has a plurality of ordinal indicia alone or with the directional index. A worker notes the placement of the directional index and the ordinal indicia when placing the crossbar a first time. The worker subsequently places the crossbar making sure the directional index and ordinal indicia appear in the same position relative to the standards and relative to the pin on the standard. |
