These are designed to secure straps and are used as railholders. They can also be used to secure an awning, luggage or equipment. They are mounted on a hard or inflatable side between any FASTen® mounting platform and a mount. One or two holders are mounted at angles of 180°, 155° and 130°. Changing the angle of the holders allows the strap to follow the contour of a boat side. A flexible shoulder pad can also be fitted to the strap. The holders can be used for stretching and securing a canopy. Set of 2 pcs.
