Content

In another aspect, the gap gauge may include a support plate connected to a hinge and a separator and the balance indicator may include a lock-out mechanism configured to prevent rotation of one of the first plate and the second plate connected to the balance indicator. The lock-out mechanism may include a set screw having a set configuration and an unset configuration, the set screw may include threads configured to engage threads within an opening. In the set configuration, the set screw may engage the pin of the hinge such that the pin does not rotate in response to a rotational force applied to at least one of the first plate and the second plate. The engaged pin may also prevent rotation of at least one of the first plate and second plate connected to the pin. In the unset configuration, the set screw is disengaged from the pin of the hinge such that the pin rotates in response to a rotational force applied to at least one of the first plate and the second plate. In one aspect, the set screw engages the pin by biasing against a planar surface of a section of the pin, the section of the pin has a D-shaped cross-section.
