Product Description
Details

Ronstan Series 40 Orbit Blocks are kilogram for kilogram of working load, 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.

  • Through extensive research and development, Ronstan replaced virtually all Metal components with high-tech polymers and fibre equivalents.
  • Dyneema Link is produced from FSE Robline SK75 fibre, which is 10 times stronger and lighter than steel, and provides the final connection from the Block to the load point.
  • It 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.
