Designed from discussion with sailors, the KBO blocks have been created to enable every sailor to benefit from soft shackle attachment: it is easier and faster to install a KBO than a regular block with stainless steel shackle. The rope shackle will not get stuck or corroded because of the loads or the years. The new KBO features a sleek design utilizing bearing technology inspired from the KBTi. The design integrates a lashing guide and allows large line diameter. KBO1 comes with rope shackle and an integrated ears that are used as a guide line. Diameter – 18mm Max Line – 6mm
