Professional pulley with ball bearings and blocking system if the speed bar is pressed. This reduces the thrust exerted with the legs and allows the speed bar to be held longer. retracting the legs locks the line roller and allows the speed bar to return to its original position.
Holding Power up to14:1
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.
