摘要:
A measuring assembly for a measuring tape device may include a blade, an end hook and an anti-rollover attachment. The blade may include a first end configured to extend from an aperture in a housing of the measuring tape device and a second end configured to be wound on a reel assembly. The end hook may be disposed at the first end of the blade to engage an object for measurement, and may extend substantially perpendicular to a longitudinal centerline of the blade to extend away from an underside of the blade. The anti-rollover attachment may be disposed proximate to the end hook at the first end of the blade such that a center of gravity of the anti-rollover attachment is spaced apart from the underside of the blade. A combined weight of the end hook and the anti-rollover attachment may be in a range between about 10 grams and about 55 grams.
