Series 55 Ratchet Mount Orbit Block - Single Cleat Swivel - Auto Features: Up to 20:1 holding power Smooth easing of sheets High performance cleating Automatic Ratchet Block Now you can enjoy the flexibility of setting up your ratchet blocks to suit yourself. Ronstan is the only company that offers a ratchet block with both auto and manual engagement modes*. In the auto mode of 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. In manual mode, the ratchet mechanism can be switched on or off as required. This is the preferred mainsheet set-up for may top sailors. Try the block in both modes and see which you prefer - you really can't go wrong. * Selected Series 55 models.  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. Its holding power is up to 21:1, almost double that of our nearest competitor. The unique sheave design has 12 gripping faces which directly resist loaded line movement. Traditional designs have only 8 faces with an angled resistance to line movement. Our Generation 2 design has straight resistance faces which both distribute the load and minimize rope wear. These faces are offset from the radial line, to draw the rope down into the gripping area when under load.  Materials: Sheave: Anodized Aluminium Ball Bearings: High compression strength carbon black Acetal Frame/Cheeks: Toughened, glass fiber reinforced Nylon Rope Link: UV stabilized, multi-strand impregnated SK75 Dyneema®

Series 40 Ball Bearing Orbit Block™ - Single - Becket - Swivel Head Core Blocks™ are a true all round solution. A tuned 2-stage bearing system provides excellent performance across the full working load range with an integrated thrust bearing feature and the resilience to handle high dynamic or static loads. Acetal sheave, alloy cheeks and stainless fixings complete the durable package. For reliability and a long service life, these blocks are the right choice for sheets, halyards and control line applications for cruising and racing. Lightweight Kilogram for kilogram of working load, BB Orbit Blocks™ are the world's lightest. The unique orbital design allows the bearing to only be in the active areas of the floating sheave. This minimises the mass of the inactive return race and hub. Weight and bulk are further reduced in the different block configurations. The ball bearing single and becket block has a through-sheave becket arrangement. The result? The lowest weight possible. Multi-sheave blocks have only single intermediate cheeks and an ultra-light and efficient head arrangement. This gives a 30% weight saving advantage over the nearest competitor. Other brands just link together their single blocks. This results in unnecessary double cheeks between each sheave, held together by a heavy steel channel across the top of the block. Highest Working Load In Its Class The orbital ball-bearing arrangement gives the largest possible bearing race diameter. This maximises load performance. The proven Ronstan 2-stage bearing system features high compression grade acetal ball bearings and a secondary full-contact bearing. This gives minimum friction across the full working load range. The floating sheave and bearing system is supported by a fiber-reinforced load frame. The design was computer modelled to be stress optimised. Features: Ultra Lightweight Low friction 2-stage Orbital ball bearing system Highest working load in its class Low profile and compact High performance cleating Swivel shackle head for unlimited block rotation Stainless steel shackle head for ultimate durability and compatibility with harsh fixing points Ultra low profile integrated becket Applications: Spinnaker sheets on dinghies, sportsboats and small keel boats to 5M(16') Halyard, vang and backstay applications on boats to 8M(26') Control line applications on larger yachts Materials: Ball Bearings - High compression stregnth carbon black Acetal Stage 2 Bearing - Glass fiber reinforced, MoS2 impregnated Nylon Frame/Cheeks - Toughened, glass fiber reinforced Nylon Sheave - Carbon fiber reinforced, PTFE impreganated Nylon Head fitting: Grade 316 stainless steel Specifications: Sheave Ø: 40mm(1-9/16") M.W.L.: 325kg(715lbs) B.
