Great rigging tool - used widely in most racing ships these days, we generally use 6mm or 8mm versions for most applications. What a terrific product!

UPGRADE - Spliced primary replacements, with handle and 4mm secondary control + your choice of block + vang key + quick pin! - Your choice of top block form Allen, Ronstan, or Harken. All blocks except for the Allen 30HL attach with a combination of dyneema loops and RF614 shackles. The bigger the block - the lesser the friction and the splicing runs a few mm further into the block extending travel over the standard set - Also comes with "quick pin attach" + upgraded Vang key where applicable
