KBO blocks simplify lashing use. Every sailor can enjoy lashing advantages with as little manipulation as standard metallic attachment blocks. It is even easier and faster to install a KBO than a regular block with stainless-steel shackle! Rope shackle and rope guide are included. They are removable, so you also can lash KBO the same way as other Karver blocks. Remove the guide and attach the KBO with a lashing, and your KBO is as light as possible. KBO blocks include side ball bearings and center roller bearings, so friction is minimized.
