    摘要: A bracket has symmetrical halves having indentations formed therein for accommodating the runner of a sled. The halves have transverse bores formed therethrough for accommodating a bolt for affixing them to each other on opposite sides of the runner. The lower parts of the halves are spaced from each other for rotatably accommodating a roller therebetween.
