Do you need a mount for Railblaza accessories that you can attach without tools on a kayak track?
Railblaza StarPort HD can be used this way with a little bit of help from StarPort HD TracMount Kit.
Simply follow the instructions or watch the video that shows you how to use it.
The spacer washers that are included are only needed on some tracks. They are put in-between StarPort HD and the hex knob, to prevent the screw bottoming out of the track.
