HHL versions have Grade 2205 stainless sheaves and bearings and are ideal for high load applications, increasingly popular on modern performance and foiling boats where small diameters lines carry high loads.

Block must be lashed through hub. The supplied lashing line must have three passes through head and hub to achieve rated load. MWL & BL are dependent on the strength of lashing. Knots, splices, stitching will generally have a lower BL than the line itself. Please note DSH-2.5GRY Soft Shackle has a BL of 450kg which is lower than the RF25109.
