Ronstan Utility Blocks

 All-Around Solutions

Utility Blocks are an ideal match for the needs of everyday recreational sailing.They are designed for low-maintenance reliability and offer a choice of sheave/bearing configurations depending on their intended use.

(All Purpose) versions are a great choice for durability and a long service life. They feature self-lubricating acetal polymer sheaves running on polished stainless steel races and perform equally well with dynamic loads and static loads.

(Ball Bearing) versions incorporate our 2-stage bearing system using ball bearings to minimise friction and a secondary full-contact bearing to maintain low friction across the full working load range.

(Special Purpose) versions are suitable for use with wire rope or where high static load capability is required.
