Series 40 Ratchet Orbital Block - Single - Automatic - Swivel Shackle Head

Automatic Ratchet
With automatic models, the ratchet mechanism is 'engages when load is applied, but turns off when released. This allows the sheet to flow smoothly and freely, which is ideal for quick release of the sheet and for gybing asymmetrical spinnakers.

Impressive holding power of the sheet ratchet block
Quite simply, Ronstan Ratchet Orbit Blocks have the highest holding power available. The sophisticated CN machined pulley features generation 2 of our cross-hole geometry. The 40 Series delivers up to 14:1 holding power, almost double that of our closest competitor.

Unique pulley design features 8 gripping faces that directly resist movement of the loaded line. Traditional designs haveno angular resistance to the movement of the line. Our Generation 2 design features straight resistance faces that distribute the load and minimize cable wear. These faces are offset from the radial line, to draw tThe rope descends into the gripping area when under load.

Simple and secure attachment
Dyneema Link installs easily and is held securely by a molded retaining clip. The flexible link can be left with one end attached to the block during assembly - no more lost shackle pins.

The system is compatible with Dyneema/Spectra strops, webbing and connection points in carbon - much more than steel loop tops or shackles.

Gentle sheet easing
With automatic models, the sheet flows smoothly and freely as soon as the ratchet mechanism disengages.

The low profile support kit allowst 0 or 90 alignment
Bracket kits feature a noise-free rubber boot. You can attach the Dyneema tie so that the block is in line with or across the standing base. This is a neat, discreet solution that allows for full articulation.
