12 mm (0.47 in) diameter glue-in bolt designed to equip sport routes. This is an expensive bolt but is not developed for equipping whole routes, but for equipping the crux or points where climbers are known to fall or abandon the route. This bolt allows the lowest hole to be used as a normal glue-in bolt and the upper hole to be used as a wire gate karabiner for the descent without having to spend time setting one up yourself. Very comfortable and simple to use. Made of high strength stainless steel. CE certified. EN 959.
