Designed from discussion between users and Karver R&D office, KBO block is born to simplify lashing use. Every sailor can enjoy lashing advantages with as less manipulation as standard metallic attachment blocks: it is even easier and faster to install a KBO than a regular block with stainless steel shackle!
The guide is removable, it is your choice to use KBO as other Karver blocks. Remove the guide and attach the KBO with a lashing, your KBO is as light as possible.
KBO includes side ball and center roller bearings. Friction ratio is minimum.
Design and material optimization makes KBO a very light block.
Guide and rope shackle make the utilization of the KBO extremely easy while keeping all the advantages of Karver blocks.
