Does Automatic chicken coop door fit the Eglu Cube MK2?

Yes, the automatic coop door comes with all the accessories required to attach your autodoor to an Eglu Cube Mk2. The only optional attachment is the control panel mounting bracket. 

All autodoors come with a mounting bracket to attach the control panel to a run or to be screwed into something. If you wish to have the control panel mounted onto the side of your Eglu Cube instead, you can purchase a bracket that slides onto the coop.
