Premium Adapter Plates
The Premium plates still use Suncall adapters, but with some extra
features. The main difference is the addition of shutters on the front of the adapters. The shutters protect from dust entering the adapter and damaging the glass or creating a bad connection. The shutters also keep harmful laser light from accidentally hitting your eye. Further, the adapters have the feature of a stable spring. This helps keep the connector from moving in the metal plate. You typically would only find this feature set with big name manufactures you charge you an arm and leg.
