Black plastic humbucker cover with legs as found on many active humbucker designs. The legs are connected to these covers, unlike normal humbucker covers, because normal humbucker baseplates cannot be soldered on plastic, as they are on standard metal humbucker covers. The legs allow the baseplate to be omitted and the pickup to be built inside the cover, which is then typically secured in the cover with an epoxy resin.
Suitable mounting screws for these covers can be found here (import size).
