This is an aluminum mount adapter for the Bullet HD 720p, Bullet HD LITE and Bullet HD PRO 1080p. The adapter connects directly to the arm and contains a female 1/4"-20 threaded steel stud that will connect to any standard male thread.
Tip: if you're using this with the 720p or Lite models, we recommend you place the mount towards the cap end of the camera. This assures the tightest and safest grip for the mount adapter.
