Doesthe narrow board model come in no gap installation or custom gap, smaller than 3/16"?

Thank you for your question! The CAMO narrow board model (CAMO Marksman Pro-NB Tool) is only available with a 3/16" gap. However, if you are using CAMO to install narrow deck boards and want a smaller gap, you do have some additional options. You can use the CAMO Marksman Edge Tool (#0345020). This tool is designed so you can use CAMO to install your deck boards without a gap between the boards. Should you wish to have a gap, you can use secondary spacers with this tool to create a custom gap size. The tool works slightly differently than the CAMO Marksman Tools as only one side of the deck board can be installed at a time, and you will need to move the tool side to side as you work your way down the board. Feel free to check out a video showing how this tool works on camofasteners.com. Another option is our CAMO Edge Pro Tool (#0345050). This is part of our CAMO Collated System. It works similarly to the CAMO Marksman Edge Tool, but is a collated screw system primarily designed for professional use. Thank you for viewing this CAMO product! -Team CAMO
