Description

Ronstan Series 40 Manual Orbit Block. Up to 14:1 holding power – highest available! Smooth easing of sheets. Manual ON/OFF ratchet selection. Easily fitted and securely retained Dyneema? link head. Manual modes allow the ratchet mechanism to be switched on or off as required. This is the preferred mainsheet set-up for many top sailors. 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 competition. 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. Discover simple and secure attachment. The Dyneema? Link is easily fitted and is retained securely by a moulded retainer clip. The flexible link can be left with one end attached to the block when fitting – no more lost shackle pins. The system is compatible with Dyneema?/Spectra? strops, webbing and carbon connection points – much more so than steel loop tops or shackles. Experience smooth easing of sheets. Manual models, the sheave cross – hole geometry eliminates the ‘shuddering’ ease-out that you can expect from traditional v-groove ratchet blocks. 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 which allows full articulation. Applications: Dinghy mainsheet systems. Mainsheet fine tune systems on sports boats & small keel boats.
