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
ultimate simplicity
For applications involving high static loads where only simple deflection and
minor trim adjustment is required, our low friction RopeGlide™ rings and
fairleads are a lightweight and robust alternative to blocks. For control line
applications our Shocks™ offer high strength and versatility in a compact form.
across the full working load range.
Special Purpose versions are suitable for use with wire rope or where high static
load capability is required.
High Load versions are designed specifically for any application where high dynamic
or static loads are expected. They feature high strength grade 2205 stainless steel ball
races and sheaves for low friction at high dynamic loads.
