RETRACTABLE RULE ASSEMBLY WITH IMPROVED BLADE OPENING

摘要

A retractable rule assembly includes wear resistant structure formed of a wearresistant material. The wear resistant structure is mounted at each lateralside of a bladeopening of the rule assembly's housing to substantially protect the plasticsmaterial at thelateral sides from wear by the lateral side edges of the blade. An alternativeretractable ruleassembly has rollers rotatably mounted at each lateral side of the bladeopening.
