Coupling Classification
Good Category
A "good" clutch having a good grip between the hand and the object is defined as a good container coupling classification or has an optimal design.
For objects that are not regulated, which are not always packed such as casting, stock, supply materials, etc., this good category coupling fulfills the record (where the grip is comfortable and easy to grip).
Fair Category
-
For an object that has an optimal design, but does not have a handle, or an object whose handle is detached.
Poor Category
An object that has a less than optimal design or a loose section or large object that is uneven, difficult to hold or has a sharp edge.
