摘要
A retractable rule assembly includes wear resistant structure formed of a wear resistant material. The wear resistant structure is mounted at each lateral side of a blade opening of the rule assembly's housing to substantially protect the plastics material at the lateral sides from wear by the lateral side edges of the blade. An alternative retractable rule assembly has rollers rotatably mounted at each lateral side of the blade opening.
