Series 40 Ratchet Orbit Block Single Auto Swivel Shackle Head
Automatic Ratchet
With automatic models, the ratchet mechanism engages when load is applied, but switches off when it's released. This lets the sheet run out smoothly and freely-great for rapid easing of the sheet and for gybing asymmetric spinnakers.
Awesome Ratchet Block Holding Power
Quite simply, Ronstan Ratchet Orbit Blocks have the highest holding power available. The sophisticated NC-machined sheave features Generation 2 of our sheave cross-hole geometry. The Series 40 delivers up to 14:1 holding power, almost double that of our nearest competitor.
Simple and Secure Attachment
The Dyneema Link is easily fitted and is retained securely by a molded retainer clip. The flexible link can be left with one end attached to the block when fitting - no more lost shackle pins.
Low Profile Stand-Up Kit Allows 0 or 90 Alignment
Stand-up kits feature a clatter-free rubber boot. You can attach the Dyneema link so that the block is aligned with the stand-up base or across it. It's a neat low-profile solution that allows full articulation.
