Description

Ronstan RF56101 Orbit Ratchet Block. Designed for applications where weight is of paramount importance. The securing loop is easily changed and we suggest that you use either a forged eye or shackle to secure the block as pressed steel fittings can be sharp and will prematurely wear the rope mounting.

Features:

  • Automatic and Manual ratchet in one block
  • Up to 20:1 holding power
  • Easily fitted and securely retained Dyneema Link head
  • Smooth easing of sheets
  • High performance cleating

Technical:

  • Sheave Diameter 55mm
  • Maximum Rope Diameter 10mm
  • Maximum Working Load 250kg
  • Breaking Load 500kg
  • Weight 78g

Materials:

  • Ball bearings - High compression strength carbon black Acetal
  • Stage 2 bearing - Carbon fibre reinforced, PTFE impregnated Nylon
  • Frame/Cheeks - Toughened, glass fibre reinforced Nylon
  • Rope Link: UV stabilised, multi-strand impregmented SK75 Dyneema

Applications:

  • Mainsheet systems on dinghies
  • Spinnaker sheets on dinghies
  • Control line applications on larger yachts
We recommend using the RF613S shackle to securely attach the block to the existing deck eye on your boat. This helps the block maintain maximum freedom of movement and reduces the risk of wear on the Dyneema loop due to sharp edges on the deck eye, then use the 8072 Rubber Boot to keep the block upright and provide a neat finish.
