This is a track mount cleat I designed to secure a paracord anchor line on a fishing kayak. The 316 stainless steel eyebolt ensures the the line is always pulling in the optimal direction against the cleat regardless of where your anchor trolley is positioned. Simply feed the line through the eyebolt and into the top of the cleat, give it a sharp tug to start it feeding into the cleat. If it starts to feed out backwards the grips inside the cleat pull the line down into it where it is narrower and will grip tighter. Using the o-ring on the eyebolt helps keep it from loosening. The M4 machine screw on the back is meant to keep it aligned with the track, and takes a small amount of force to prevent the cleat from flexing. It is printed in black PETG plastic, which is highly UV resistant. It is similar to the material soda bottles are made from. Includes: 1 3D printed cleat, 1 M4 machine screw, 2 printed M4 t-nuts, 1 316SS eyebolt with t-nut, O-ring and washer for the eyebolt and an M4 hammer nut that can be used in place of the printed t-nuts.
