Product Information

Ronstan Lashing Block

Ronstan Series 20 BB Orbit Blocks? features a unique Lashing head

  • Building on the latest trends in grand prix dinghy and ocean racing for lighter weight fittings and hardware, this block replaces the steel head post and shackle arrangement of traditional blocks thus providing a lighter weight option.
  • The Maximum Working Load and Breaking Load of the assembly (Block + Lashing) are generally limited by the strength of the rope and the joining method.
  • Knots, splices, stitching, etc. will generally have a lower Breaking Load than the rope itself. It is possible to use up to 4mm lashing line for lashing the RF25109 running the lashing around as a single strand however, a neater result with more secure knotting can be achieved by using the smaller super strong line size provided (e.g. 1.7 - 2mm) passed through multiple times.
  • The RF25109HL Series 20 Orbit Block? is supplied with 750mm of 2mm diam. single braid Dyneema? lashing line.
  • For best results, the lashing must be attached to a mounting point with a smooth, well-rounded profile.
  • Avoid attaching directly to fittings with sharp edges or rough surfaces that may damage the lashing through abrasion or point loading. Instead, use a shackle with a smooth surface between the lashing and the fitting.
  • Regularly inspect the lashing for damage, if found replace immediately.

IMPORTANT: To meet breaking loads this block must be lashed with the lashing, strop, or link passing through the hub.
