The Rhino Slider comes with a standard 3⁄8” mounting post installed. We include a 1⁄4-20 mounting screw as well. We recommend screwing the spare mounting screw into one of the ends of your slider for safe keeping.
To change mounting screws use the spare screw to push out the plastic keeper from the top. When the keeper is removed slide the mounting screw out and down and slide in the new screw up from the bottom. Replace the plastic keeper and you’re ready to go.
