The Mini-Clouds can be placed anywhere under the bottom of the component to balance the load. As with the Cloud 10 and Cloud 11, each ball has an optimal load of 10 lbs and a capacity of 20 lbs. So a set of Mini-Clouds is perfect for components weighing 30-40 lbs. For heavier components, simply add more Mini-Clouds (Mini-Clouds are available only in sets of three).
Since the Mini-Clouds do not require a top plate, their profile is lower than that of the Cloud 10 or Cloud 11, which is beneficial when shelf space is limited. Their base has the same double thickness as the Cloud 11’s bottom plate, with a deep well and dimple; the balls won’t roll off the dimples unless you deliberately push really hard.
