Midrange Blocks > Hexaratchets
The Mid-Range Hexaratchet offers a holding power of 15:1 at 180° of wrap, yet allows crew to ease line instantly. An on/off switch disengages the ratchet mechanism in light air.
The 1571 and 1572 reverse ratchets pair with the 1549 and 1550 for jib and spinnaker sheet applications where ratchet rotation is in opposite directions and ratchet switches should face up.
Mid-Range triples with ratchets and cams on adjustable arms build powerful, low profile 5:1 or 6:1 tackles for mainsheets, vangs, or backstay adjusters.
