Abstract
An end hook may include a stem portion extending in a first plane from a proximal end to a distal end and an engaging portion. The end hook may be operably coupled to the measuring device at the proximal end. The engaging portion may be defined by a set of teeth having external lateral edges that define a hook width therebetween. The engaging portion may extend away from the stem portion by an engaging length. Each of the teeth may include a portion thereof that extends away from the distal end of the stem portion in a second plane that is substantially perpendicular to the first plane. Each of the teeth may further include a portion thereof, proximate to a distal end of the teeth, that bends out of the second plane to form an engaging angle. The hook width may be in a range between about 16.5 mm and about 21 mm, and the engaging angle may be greater than about 45 degrees.
