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 patented sheave cross-hole geometry. The Series 40 delivers up to 14:1 holding power, almost double that of our nearest competititor.
The unique sheave design has 8 gripping faces which directly resist loaded line movement. Traditional designs have an angled resistance to line movement. Our Generation 2 design has straight resistance faces which both distribute the load and minimise rope wear. These faces are offset from the radial line, to draw the rope down into the gripping area when under load.
Simple and secure attachment
A swivelling shackle is used for attaching the block, which allows for unlimited twists of the block.
Smooth easing of sheets
With the ratchet mechanism disengaged the sheave and sheet runs out smoothly and freely. When the ratchet is engaged, the sheaves cross hole geometry eliminates the 'shuddering' ease-out that you can expect from traditional v-groove ratchet blocks.
