Series 25 T-Track - Composite Slide - 102mm(4") For small keel boats and sportsboats T-track jib leads are a great blend of performance and functionality in a simple, efficient package. Composite slide bodies with plunger stops run on anodised aluminium track, and allow quick and easy manual adjustment. Lightweight Composite jib lead cars continue the design philosophy of the award winning Ronstan BB and RT Orbit Blocks™, with virtually all metal components now replaced with high-tech polymers and fibre equivalents. The car design has been modelled and optimised using finite element analysis and rapid prototyping techniques to achieve maximum strength-to-weight characteristics. Orbit Block™ models use a Dyneema® Link which is 10 times stronger and lighter than steel, to provide the articulated connection between block and car. Integrated Functionality The clever 2-piece car body is molded from a composite material that delivers low friction on the alloy track without the need for separate inserts. It also provides the required mechanical strength without the weight and corrosion drawbacks of metal parts. An integrated becket at the forward end of the car suits 2:1 sheet systems and the removable threaded pin allows easy fitting of alternate blocks and accessories. Low Profile and Compact Sleek styling and the positioning of the attachment pin provide a low lead aft for the lead block. The Dyneema® Link allows full articulation. The plunger stop button has a flush finish and the contoured form of the car eliminates the chance of lines and sails becoming snagged. Precise Adjustment The ergonomic plunger stop toggle combined with low friction of the car body allows for easy one-handed adjustment. The toggle is located at the rear of the car for easy access from the cockpit on sports boats and small keel boats. An arrow is located on the side to indicate the position of the stop for repeatable settings. A 'Racing' track has 25mm(63/64") stop hole spacing for even more precise control of the car position and sheeting angle. Features: Low profile and lightweight Removable attachment pin to suit either Dyneema® Link or a shackle Integrated becket for 2:1 headsail sheet systems Applications: Headsail sheet leads on boats up to 8M (26').

Series 55 Ratchet Mount Orbit Block - Single Becket Cleat Swivel Features: Up to 20:1 holding power Smooth easing of sheets High performance cleating Automatic ratchet block 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: Anodised Aluminium Ball Bearings: High compression strength carbon black Aceetal Frame/Cheeks: Toughened, glass fibre reinforced Nylon Rope Link: UV stabilized, multi-strand impregnated SK75 Dyneema®

Series 40 Ball Bearing Orbit Block - Single - Becket - Cleat - Swivel Head Features: Ultra Lightweight Low friction 2-stage Orbital ball bearing system Highest working load in its class Low profile and compact High performance cleating Lightweight Kilogram for kilogram of working load, BB and RT 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 minimizes 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 It's Class The orbital ball-bearing arrangement gives the largest possible bearing race diameter. This maximizes 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 modeled to be stress optimized. Applications: Mainsheet systems on spinnaker sheet on dinghies to 5m (16ft) Spinnaker sheets on dinghies, sportsboats and small keel boats to 5m (16ft) Halyard, vang and backstay applications on boats to 8m (26ft) Control line applications on larger yachts Materials: Ball Bearings - High compression strength carbon black Acetal.

Series 45 Stand-Up Core Block - Swiveling 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. Universal Bearing Dynamic and high static load performance The Ronstan Universal Bearing incorporates our proven 2-stage bearing system Stage 1 - Under moderate loads, Acetal ball bearings ensure minimum friction Stage 2 - Under heavy loads, where deformation of ball bearings alone would result in increased friction, a sliding Acetal bearing on a polished stainless steel race takes over, maintaining low friction performance Additionally the ball bearings are configured to act as a thrust bearing between the sheave and cheeks, preventing the sheave from rubbing on the cheeks and causing friction when the line lead in and out of the block isn’t perfect. Particularly important for cheek blocks Alloy Cheek Plates Block cheeks are manufactured from the highest quality alloy for maximum strength. Material optimization and the cut-away design minimizes weight and allows easy fresh water rinsing of salt and debris from the bearings.  Cheek design has been further styled with flaring at the block throat and reduced gap between the cheek and sheave, minimizing rope wear. Features: High dynamic and static load capacity Efficient 2-stage bearing system Ball bearings to counteract side thrust loads Class leading performance and sleek, contemporary styling Durable aluminium alloy cheek plates Central hub hole can be used as a becket take-off or tie-up point Features a strong cast padeye base with a swivel head post to allow full rotation and articulation Applications: Ideal for mainsheet, halyard and spinnaker sheet applications on boats to 10M (33') Various control line applications on larger yachts Alloy sheave models are available for use with wire Materials: Sheave: U.V. stabilised Acetal Cheek body: Aluminium Alloy Ball Bearings: High compression strength carbon black Acetal Shackle, head post & hub: Grade 316 stainless steel
