Notes:
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.
The incredible Series 20 Orbit Block™ is capable of loads up to 250kg (550lb) while weighing a mere 9 grams. It’s so light that it needs to be lashed down!
