When we manufacture the parts to either the standard (small) or cargo (large) handles, it is possible for all the parts to be within tolerance, but when assembled, there is an excessive amount of play between the snap ring and base, allowing a gap between the cover and base. It was originally thought that this might be an issue, but Beech determined it was not, so we no longer make the KH301-11 washer. The washer was the same for either handle and was just a small passivated stainless steel shim material.
