Ronstan Series 30 Ball Bearing ILCA® Top Vang Block

High load stainless steel single sheave block with vang key. The RF34108HL is a purpose designed ILCA® top vang block. The top vang block cheeks are made of grade 316 stainless steel with a hard wearing black coating. High load blocks are designed specifically for any application where high dynamic or static loads are expected. They feature a high strength grade 2205 stainless steel sheave & hub together with a triple bearing race to maintain low friction at very high loads.

Ronstan’s ILCA® lower vang unit is the new benchmark in design and performance. Thoroughly tested on the water by leading ILCA® sailors, the vang unit features optimised geometry to minimise line chafe and friction which provides a purchase advantage, and easy cleating and releasing to stay in full control when playing the vang from any angle while inboard or hiking.

The primary purchase sheave features Ronstan’s high load, low friction, stainless steel HHL sheave. Geometry of the cleat arm pivot point is close to the clevis pin attachment to minimise stress on the mast attachment point.
