Abstract
Disclosed is a rule assembly having a housing, a reel rotatably mounted in the housing, an elongated blade wound on the reel and extendable through an opening in the housing, and an end hook member attached to the elongated blade. A hook portion extends downwardly below a bottom surface of the housing when the blade is in a fully retracted position. The housing has an opening having an upper portion disposed above the blade, and a flexible cover overhanging the opening to inhibit or prevent penetration of debris therein. The cover is flexed by the end hook member upon impact by force (e.g., when dropped) and permits movement of the end hook member into the opening to reduce deformation of the end hook member. Optionally, a grip cover made of elastomeric material is provided on the housing and the cover is part of the grip cover.
