Core Block™ - 60mm
Ronstan's Universal Bearing, incorporating their proven 2-stage bearing system, provides dynamic and high static load performance:
Stage 1 - Under moderate loads, Acetal ball bearings ensure minimum friction.
Stage 2 - Under heavy loads, where deformation of ball bearings alone would result in increased friction, a sliding Acetal bearing on a polished stainless steel race takes over, maintaining low friction performance.
Trunnion snap shackle allows both 360° rotation and side to side articulation. Snap shackle internal clearance - 3/4" (20mm). The RF64103 block with trunnion snap shackle head is an ideal utility/emergency block and can be attached to toe rail. It's also an ideal 2:1 halyard block with quick attachment & removal.
