Block safe working load: The lashing may hold a higher load.
Manufacturer part #: PF040031
Simple, reliable and effi cient - the Karver KB block combines both freedom of attachment and extreme safety. Launched 8 years ago, the KB block has won several awards including the famous Freeman K. Pittman Award (2006) granted by SAIL Magazine. Innovative, its design and its multiple attachment possibilities make this block super versatile.
Self-lubricating plain bearings, KBc blocks are ideal for applications when the line is required to run under very high load for a short distance (backstay, Cunningham, boom vang, out haul, etc).
Light Weight
Compared to traditional blocks (at equal working load), the use of soft attachment through the center of the block reduces weight up to 50%.
Versatility
With the use of lashing materials, multiple attachments are possible when installing the block (e.g Backstay sytems), or even just to tie it up (eg. To prevent capsize).
Safety
Attachment through the center prevents the running line from becoming disconnected from the lashing line if the block fails under extreme load.
Silent
Unlike metallic shackles, the use of textile attachments avoids metallic impacts on deck which contributes to keeping the boat quiet.
