Series 40 Orbit BB Quin Block with Swivel ShackleThe Series 40 ball-bearing Orbit Blocks™ provides the perfect balance of strength, performance, and reliability. They offer class-leading dynamic and static load ratings, the highest available in this size of performance blocks. Lightweight and strong toughened glass fiber reinforced nylon cheeks replace stainless steel straps used in traditional utility blocks - the perfect balance of performance and reliability.As well as traditional single swivel blocks, the range includes single and double sheave lashing or soft attachment options through to multiple sheave blocks including those with quad and quin sheaves. The range is highly versatile allowing a multitude of possible systems right up to a 12:1 purchase mainsheet system for off-the-beach performance catamarans.Series 40 Orbit Blocks™ are fitted with our carbon-reinforced C-Cleat™ for secure rope holding with low entry and exit efforts, and fairleads for fast action from any angle. Cleat arms are made from stainless steel and adjustable for setting your preferred cleating angle.Ball Bearing versions incorporate our 2-stage bearing system using ball bearings to minimize friction and a secondary full-contact bearing to maintain low friction across the full working load range.High Load versions are designed specifically for any application where high dynamic or static loads are expected. They feature a high-strength grade 2205 stainless steel sheave & hub together with a triple bearing race to maintain low friction at very high loads.Features: Class-leading dynamic and static load ratings Lightweight, yet strong. Toughened, glass fiber reinforced nylon replaces stainless steel straps used in our traditional utility blocks Low friction 2-stage ball bearing system for efficient and effortless trimming Soft attachment, lashing and traditional swivel shackle head options Low profile and compact High performance cleating Applications Mainsheet systems and spinnaker sheets on dinghies, off-the-beach catamarans and sportsboats to 8m (26ft) Halyard, vang and backstay applications on boats to 9m (30ft) Control line applications on larger yachts Specifications: Sheave Ø: 1-9/16 in.

Series 30 Ball Bearing Block Single Becket Option LashingBall Bearing Blocks™ boast the highest strength-to-weight ratio available.  This is achieved through all-composite reinforced polymer materials and multiple attachment options. Their precision design provides the optimum number of ball bearings for minimum friction while weight reduction is achieved through the use of fibre-reinforced composites in the block head, cleat arms and beckets. Highest Working Load in its ClassThe proven Ronstan 2-stage bearing system (Series 30 and larger) features high compression grade Acetal ball bearings and a secondary full-contact bearing. This gives minimum friction across the full working load range.The sheave and bearing system is supported by a fibre-reinforced load frame, computer modelled and optimised using advanced stress analysis methods. The Dyneema® Link, used in multi-sheave blocks, is produced from high spec SK75 fibre, which is 10 times stronger and lighter than steel, and provides the final connection from the block to the load point. Simple, Versatile & Secure AttachmentThe single block is easily lashed to an attachment point, and can also accept Dyneema® Links and shackles for a variety of efficient attachment alternatives. The Dyneema® Link used in multi-sheave blocks is easily fitted and secured by a removable pin. The Dyneema® Link can also be removed and replaced by a shackle, custom lashing or strop.These blocks are far more compatible with Dyneema®/Spectra® lines, carbon laminate connection points and webbing than traditional blocks with steel loop tops or shackles.Low Profile & CompactThe two way head in the single lashing block allows for alignment at 0° or 90° orientation, while the single swivel block allows for full articulation.The flexible Dyneema® Link used in multi-sheave blocks provides 0° or 90° orientation. It connects directly to the head of the block rather than to an intermediate head post. This reduces weight and gives the lowest possible profile while allowing full articulation. Beckets have been carefully designed to minimise height.Features: Lightweight Highest working load in its class Secure, versatile and secure attachement Low profile and compact Ultra low profile thru-sheave becket Self-lubricating Nylatron® sheave and full contact bearing for high dynamic loads Applications: Mainsheet systems and spinnaker sheets on dinghies to 5M(16') Halyard, vang and backstay applications on boats to 5M(16') Control line applications on larger yachts
