Used in combination with the Action Cam Housing Adapter, it allows mounting of underwater housings for action cams on the brackets. It attaches to the Carbonarm trays using the included screw and must be combined with the Action Cam Housing Adapter. To increase the mounting height of the housing on the bracket, the Male-Female Adapter for Action Cam can be inserted between the Tray Adapter and the Housing Adapter, acting as an extension. This adapter is made of polycarbonate and features stainless steel screws and thread. A plastic washer and Allen key are included. Photographic thread: Screw diameter: 1/4″ Threads per inch: 20 tpi Attention: this adapter attaches to the bracket with a single screw. For a more stable mounting of the housing on the bracket, we recommend using the alternative accessory Kodak screw kit with Allen key, which allows attachment with two screws.
