Karver KB Series Bearing Blocks

Simple, reliable and efficient - the Karver KB block combines both freedom of attachment and extreme safety. Compared to traditional blocks, the use of a soft attachment allows for multiple attachments when installing the block while reducing weight up to 50%. Unlike metallic shackles, the use of textile attachments avoids metallic impacts on deck which contributes to keeping the boat quiet.

Karver KB Range blocks are assembled with roller bearings for extremely low friction and are adapted for general usage.

Karver KBC Range blocks are assembled with self-lubricating plain bearings and are ideal for applications when the line is required to run under very high loads for a short distance (backstay, cunningham, boom vang, outhaul, etc.).
