8:1 Downhaul Primary Assembly - Allen 20/30mm High Load Blocks
For sailors just wanting to update an existing system to a 8:1 system, the primary line assembly comprises and Allen 30mm High Load block and an Allen 20mm High Load blocks securely spliced using SK78 Dyneema. These new blocks with stainless steel sheaves and bearings run amazingly well. The length of the primary line for Standard MkII is approx. 80cm from loop end to the top of the upper block. The length of the primary line for Radial/Standard MkI/4.7 is approx. 70cm from loop end to the top of the upper block. This is so the top block sits at approx. boom height in the 'released off' position to help avoid the blocks getting caught in the gooseneck. If you want any other length (+/- 20cm) just add a note to the order. Lengths are 10cm less for top of kicker attachment.
