The Kraken Lens Adapter gives you a 52mm and 67mm threaded port on the front of the Kraken Smartphone Housing and the Smartphone Housing Pro. This will let you attach wet lenses like the Kraken Wide Angle or Macro Lenses. It will also accept any other 52mm or 67mm thread wet lens.

The complete kit includes an attachment plate with a 52mm ring adapter. The plate is attached to the front of the housing with the included bolts and washers. The position of the adapter can be adjusted both vertically and horizontally by loosening the bolts with the included hex key. A 52mm - 67mm step-up ring is also included.
