Dek-It mounts do not come with mounting hardware because every install and boat is different so every install will require different mounting hardware.
We suggest to first determine exactly how your Dek-It mount will mount on your boat, then determine what kind of mounting hardware you will need and then head to your local hardware store to pick up what you need.
Below are videos that Dek-It Mount users have recorded on how they have mounted their Dek-It mounts to help give you ideas for your project.
