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 a permanent end hook member attached to the elongated blade with a first hook portion. The rule assembly further has another or second end hook member that is removably attachable to the elongated blade with a second hook portion. Each of the permanent end hook member and second end hook member are capable of limited movement relative to the blade between an extended position and a retracted position. The second hook portion can extend in a direction opposite to that of the first hook portion. A forward surface of the second hook portion can be aligned with a forward surface of the first hook portion to form a larger surface area for engagement with a workpiece.
