Ronstan Series 30 HHL Orbit Block Lashing Head — User Instructions

Lashing the Block

  • To meet the stated Breaking Load the block must be lashed with the lashing, strop or link passing through the central hub. The Breaking Load depends on the strength of the lashing.
  • The BL of the assembly (block + lashing) is generally limited by the rope and the joining method; knots, splices, stitching, etc. are generally weaker than the rope itself.
  • Up to 8mm lashing line can be used in a single pass through the hub, but smaller line with multiple passes gives a neater result and more secure knotting.
  • The block is supplied with 200mm (8") of 1.0mm (1/16") diam. Dyneema® core twine to secure the lashing line to the head.
  • Attach to a mounting point with a smooth, well rounded profile to avoid chafe. On sharp-edged or rough fittings put a smooth shackle between lashing and fitting.

Becket Option

  • The central hub can be used as a becket.

Shackle Mounting Option

  • Example: RF614 narrow shackle with 3/16" pin and RF9004-11 Dyneema® Soft Link.
  • With these accessories as the mounting, the BL is reduced to 1300kgs (2860lbs).

Inspection

  • Regularly inspect the lashing for damage and replace it if necessary.
  • Lashings degrade from fatigue, wear and UV exposure: inspect them as part of your regular maintenance, like the rest of the running and standing rigging, and replace them if they show significant wear or fibre damage.

BB = Ball Bearing. MWL = Maximum Working Load. BL = Breaking Load.
