Use the Lindell Ice Rig Tube Bracket in your portable. Secure it to one of the support post with 2 zip ties. Then mount your Lindell Ice Rig or Lindell Rod Holder in the Tube Bracket. Be sure the Tube Bracket is on a post that will access the ice hole. Or in converse, be sure to drill your ice hole where it can be accessed from your Lindell Ice Rig or Lindell Rod Holder.
