Ronstan Series 40mm Fiddle Orbit BB Block

The orbital ball-bearing arrangement gives the largest possible bearing race diameter. This maximises load performance. The proven Ronstan 2-stage bearing system features high compression grade acetal ball bearings and a secondary full-contact bearing. This gives minimum friction across the full working load range.

Becket fiddle blocks use a Dyneema Link attachment for the sheet termination and are suitable for both spliced and un-spliced lines. If you need additional purchase, a becket take-off can be simply added to any fiddle block version just by adding a Dyneema Link.
