KARVER K-BLOCKS EXCLUSIVE ADVANTAGES:
- SAFETY: lashing through the block center significantly increases safety in event the block fails. The line running through the block remains captive by the lashing, not allowing it to completely break free.
- LIGHT FOR BOATS WEIGHT: These exceptionally light blocks, combined with the lashing method of attachment, allow to reduce weight up to 50% as compared to conventional block with similar working load.
- ATTACHMENT: lashing through the center of the block offers unlimited applications and mounting possibilities (double lashing, becket...), the block can be tied up easily.
- REDUCED NOISE: lashing block greatly reduces noise created by mechanical attachments such as marine shackles and marine pins.
KARVER K-Blocks are available for safe working loads going from 0.2 to 4.5 T.
