Ronstan 30 mm Series 30 Orbit Triple Block - RF35332

Item # 879830

Description

The Ronstan 30 mm Series 30 Triple Orbit Block with Cam Cleat (RF35322) boasts the highest strength-to-weight ratio available. This is achieved through all-composite reinforced polymer materials. Their precision design provides the optimum number of ball bearings for minimum friction while weight reduction is achieved through the use of fiber-reinforced composites in the block head.

Features:

  • Lightweight
  • Highest working load in its class
  • Secure, versatile and secure attachment
  • Low profile and compact
  • Ultra low profile thru-sheave becket
  • Low friction 2-stage ball bearing system provides consistent performance over the full working load range

Applications:

  • Mainsheet systems on dinghies to 5 m (16 ft)
  • Spinnaker sheets on dinghies to 5 m (16 ft)
  • Control line applications on larger yachts

Specifications:

  • Safe working load: 990 lb (550 kg)
  • Breaking load: 2425 lb (1100 kg)
  • Weight: 4.5 oz (126 g)
  • Sheave diameter: 1-3/16" (30 mm)
  • Maximum line size: 5/16" (8 mm)
  • Materials:
    • Sheave: High compression strength carbon black Acetal
    • Ball Bearings: High compression strength Acetal
    • Frame/Cheeks: Toughened, glass fiber reinforced Nylon
    • Link: UV stabilized, multi-strand impregnated SK75 Dyneema®

Ronstan Ball Bearing Orbit 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 fiber-reinforced composites in the block head, cleat arms and beckets.

Lightweight Kilogram for kilogram of working load BB Orbit Blocks™ are the world's lightest. To gain peak performance, Ronstan engineered out the heavy steel load straps, head post, shackle and cleating accessories. Through extensive research and development, Ronstan replaced virtually all metal components with high-tech polymers and fiber equivalents. 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. Other brands just link together their single blocks with a heavy steel channel across the top of the block, with unnecessary extra cheeks adding extra weight and bulk not found in Ronstan Orbit Blocks™.

Highest working load in its class The 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 fiber-reinforced load frame, computer modeled and optimized using advanced stress analysis methods. The Dyneema® Link, used in multi-sheave blocks, is produced from high spec SK75 fiber, which is 10 times stronger and lighter than steel, and provides the final connection from the block to the load point.

Simple, versatile and secure attachment 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 and compact The 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.

High performance cleating Ronstan BB Orbit Blocks™ feature strong, lightweight fiber-reinforced cleat arms optimized at the required cleating angle. Race-proven, carbon-fiber reinforced Ronstan C-Cleats give secure rope holding with low entry and exit efforts, and are fitted with fairleads for fast action from any angle
